Shared Element Transition only runs once when navigating to screen in parent navigator

[jparkrr]

Description

Thanks for working on shared element transitions! I noticed an issue when I was trying it out in my existing app. If you have two nested native stack navigators, when navigating from a screen in the child to a screen in the parent, the transition seems to only happen once.

Is this an intended use case that should be working? I use it in my app for hiding a tab bar on certain screen as recommended by react-navigation docs. In my app I use a stack as a parent of a tab navigator, but the bug also occurs with two stack navigators.

Steps to reproduce

I've reproduced by modifying the existing nested navigator example in your testing app. See changes here: jparkrr#1

1. Tap to navigate in the parent stack (Transition runs)
2. Go back (Transition runs)
3. Tab again to navigate in the parent stack
4. Notice the transition doesn't run

@jparkrr Thanks for flagging this! Will be useful to fully polish the implementation

@bartlomiejbloniarz You're welcome! I'm wondering for my own planning purposes when you folks will be working on a round of SET fixes. In the next couple of weeks or further in the future?
