Spec updates are in https://github.com/whatwg/html/pull/10919
For the most part, the updates revolve around the deferred commit
handling (with precommitHandler). Updates to redirect allow more
options. A committed promise now exists on the transition since commits
can be delayed. Tests were made zoneless for easier debugging and
timeouts were reduced.
PR Close#62017
This moves the `FakeNavigation` implementation to the primitives folder
so its implementation can be shared with Wiz. This class was initially
copied directly from the Wiz implementation, with some small modifications.
There will still need to be some work done to align the implementations
and fix anything internally that needs adjusting.
