Transition back not triggered

**I searched on the issues but didnt find something realted to my issue.**

I have this structre with React Navigation 5

Screen 1: Does not have any shared element registered
Screen 2: Shared element registered to animate Screen 1 <-> Screen 2
Screen 3: Shared element registered to animate Screen 2 <-> Screen 3

Screen 1 <-> Screen 2 Works like a charm for push and back.
Screen 2 -> Screen 3 works only the push transition, but transition back is not triggered

If I remove the shared elements registration on Screen 2 (losing the animation between Screen1 <-> Screen 2) the animation of Screen 2 <-> Screen 3 works.

Reproduce the three-screen React Navigation 5 structure described in the issue, keeping shared elements on Screens 2 and 3 while testing both push and back transitions. Trace the shared-element transition entry points involved in the back navigation; done means the Screen 2 to Screen 3 transition runs when navigating back without removing Screen 2's registration.
