I can reproduce this. It seems like if you remove the tab from the collection, "Jump back in" to the current tab, then go back to the share collection popup, it will register the change finally.

There is another problem I've noticed where tabs themselves (not just collection entries) reappear if the app goes to sleep, but I'm not sure if there's already an issue for that.

This issue is no longer reproducible on the latest Beta 105.0b2, and the latest Nightly 106.0a1 (2022-08-26).
Tested with an Oppo Find X5 (Android 12).
Closing the ticket as verified.
