Summary
This adds a failing test for #3764.
I also had to upgrade React to v19 for the test to fail as expected:
(the relevant part is the "Cannot update a component …")
There's however more work necessary for the React 19 upgrade (other tests are failing due to the deprecated test renderer). Maybe you want to do the React 19 upgrade in another PR?
I hope this can be used for #3769 to verify the the bug is fixed.
