This is a minimal implmentation which just focuses on registering parent shadow roots in `SharedStylesHost` correctly.
We don't currently reference count usage of host values, meaning that as soon as we call `removeHost`, all styles are removed from it, even if other components relied on them. Therefore there is no good way to know whether styles are still needed or not, leaving us with the choice of either leaking them longer than necessary or destroying them while another component still needs them. The compromise I'm using here is to delete styles when destroying a component under a shadow root (based on the assumption that only one component will exist per shadow root) and to leave styles when destroying a component in the main document (based on the assumption that dialogs being destroyed should not impact the main application).
Neither assumption is totally safe to make, but we're hoping this is a viable balance for the moment. In the future we should look into lifting these restrictions to better support those use cases while properly reference counting usage of hosts in `SharedStylesHost`.
I also added some small tests to confirm that SSR styles are not duplicated, as an earlier implementation accidentally duplicated them. This should ensure we don't repeat that mistake.
This commit updates provideClientHydration to automatically enable incremental hydration by default. It also introduces a new withNoIncrementalHydration feature for opting out, adds conflict safety checks, and includes a schematic migration.
This is to align the shape of the method with `createComponent`
BREAKING CHANGE:The second arguement of appRef.bootstrap does not accept `any` anymore. Make sure the element you pass is not nullable.

The default change detection strategy is now OnPush.
BREAKING CHANGE: Component with undefined `changeDetection` property are now `OnPush` by default. Specify `changeDetection: ChangeDetectionStrategy.Eager` to keep the previous behavior.
This fixes a regression bug that resulted in reordered elements not getting properly removed from the DOM. Reused nodes were not being cleared out in this situation.
fixes: #67728
This commit re-introduces support for nested leave animations with a critical adjustment to prevent cross-component blocking. Wait for nested inner `animate.leave` transitions natively only when they exist within the same component's view or its embedded tracking structures (like `@if` and `@for`).
This resolves the issue where route navigations and parental destruction would excessively stall by traversing down into child component architectures to wait for their distinct leaf animations.
BREAKING CHANGE: Leave animations are no longer limited to the element being removed.
Fixes#67633
When routing between two different routes, child animations were not finishing, causing elements to be left behind in the dom. The fix ensures the proper fallback is handled to avoid automatically cancelled custom events. This ensures the animation-fallback cancelling the animation actually completes, and ensures the element is removed.
fixes: #67400
