Separate direct from curried calls of `describe`/`it` modifiers
(direct: `skip`, `only`, etc.; curried: `runIf`, `each`, etc.)
and perform the required patching to them.
Fixes: #69748
(cherry picked from commit e23541b263)
Initialize `zoneSymbolEventNames` and `patches` with `Object.create(null)` instead of `{}`.
This is a hardening change rather than a fix for an exploitable vulnerability. Calling `addEventListener('__proto__', fn)` is not directly attacker-controlled; its presence already implies an application bug. However, if such a call does occur, the current implementation can behave unexpectedly depending on the environment.
For `zoneSymbolEventNames`, accessing `zoneSymbolEventNames['__proto__']` on a plain object invokes the inherited `__proto__` accessor and returns `Object.prototype`, which is truthy. This causes `prepareEventNames()` to be skipped, leaving `symbolEventName` undefined and eventually leading to a runtime error when `window['undefined'] = []` is executed.
In Node.js environments running with `--disable-proto=throw`, the assignment:
```ts id="z8n4qm"
zoneSymbolEventNames['__proto__'] = {};
```
throws immediately because it triggers the disabled `__proto__` setter.
The `patches` registry has a similar issue. A `__proto__` key passed to `__load_patch()` bypasses the duplicate-patch check and reaches:
```ts id="f3v7kx"
patches['__proto__'] = fn(...);
```
which invokes the `__proto__` setter and changes the prototype of the `patches` object.
Using `Object.create(null)` removes the inherited `__proto__` accessor entirely, causing these keys to behave like ordinary properties rather than interacting with JavaScript's prototype machinery.
As part of this change, `patches.hasOwnProperty(name)` is also updated to:
```ts id="n2c8wp"
Object.prototype.hasOwnProperty.call(patches, name)
```
since null-prototype objects do not inherit `hasOwnProperty`.

Ensure that when a custom object with a 'rejection' property is thrown as a raw promise rejection, the unhandled promise rejection error logger does not crash with a TypeError while trying to access undefined zone properties.
Also wrap microtask queue draining and task frame counter updates with defensive try-finally blocks to guarantee internal scheduler states are properly reset under any potential call stack exception unwinding scenarios.

To support `fakeAsync` usage while using `vitest` as a test runner, Zone.js
now provides patching when using the `zone.js/testing` package import.
This patching is similar to that of the existing jasmine, mocha, and jest
functionality.

These changes are essentially the same as those introduced in
angular#45273, but they include backward compatibility
for applications that explicitly rely on the order in which microtasks are drained.
This is critically important for our code and other third-party code, which is
beyond our control, to work properly. If a microtask is scheduled within an event
listener to be executed "later", it should indeed be executed later and not synchronously,
as this would break the expected flow of code execution.
The simple code that reproduces the behavior that exists now:
```ts
Zone.current.fork({name: 'child'}).run(() => {
const div = document.createElement('div');
div.style.height = '200px';
div.style.width = '200px';
div.style.backgroundColor = 'red';
document.body.appendChild(div);
function listener() {
Promise.resolve().then(() => {
div.style.height = '400px';
});
}
div.addEventListener('fakeEvent', listener);
div.dispatchEvent(new Event('fakeEvent'));
console.log(div.getBoundingClientRect().height); // 400
});
```
The code above logs 400 as the height, but it should actually log 200 because the
height is updated in a microtask within the event listener.
When using Angular with microfrontend applications, especially when other apps might be
using React, zone.js can disrupt the classical order of operations. For example, when using a
`react-component/trigger`, it schedules a microtask within an event listener using
`Promise.resolve().then(...)` to determine whether the event needs to be re-dispatched.
The event is re-dispatched when the layout has changed, which is why a microtask is used.
With this change, we introduce a global configuration flag,
`__zone_symbol__enable_native_microtask_draining`, to allow consumers to enable
microtask draining within a browser microtask.
This flag is necessary to prevent any breaking changes resulting from this modification.
The previous attempt to address this issue caused a significant number of failures in g3.
Therefore, we are hiding that fix behind the configuration flag.

When Zone patches Promise, it uses ZoneAwarePromise. The new Promise.try API was undefined on ZoneAwarePromise, making it unavailable when zone was present. This change gracefully passes through Promise.try to the native Promise implementation, if available, without patching it to execute in the right zone (our stance is not to add new patches but avoid destructively making new APIs unavailable).

When using `file:` renovate updates fails due to ` ERR_PNPM_LINKED_PKG_DIR_NOT_FOUND ` this is due to a different behaviour between `link:` amd `file:`. `link:` however will not fail when the directory does not exist.

Benefits of auto-ticking mock clocks have been described in other PRs,
such as https://github.com/jasmine/jasmine/pull/2042 and
https://github.com/sinonjs/fake-timers/pull/509. In short, `fakeAsync`
cannot work when some tasks are required to be truly async, such as XHRs
or observers like ResizeObserver. In addition, auto ticking mock clocks
can be applied to tests without the tests then needing to update
everything to manually flush timers.

This ensures that test functions with arguments (e.g. `it.each` in jest)
are forwarded to the test function. This does not apply to jasmine,
which assumes the only arguments needed would be the `done` function.
