Compatible with screens in different stacks?

I am looking to implement shared element transitions in our application.

I want to navigate from a screen in one stack, to a screen in another stack.
The stacks are each in their own tab screen, like so:

Tab Navigator
- Tab 1
- - Stack 1
- - - Screen 1
- Tab 2
- - Stack 2
- - - Screen 2

I want to navigate from Screen 1 to Screen 2 using a shared element. Is this possible? I cannot find any mention of this use case or any other issues which could address the navigation between different stacks.

What are my options?

The issue names no files, tests, or entry points. Start by tracing how shared element transitions connect the two tab-contained stacks, then determine whether cross-stack navigation is supported or requires a new design. Done would be a documented, reproducible option for navigating from Screen 1 to Screen 2 with a shared element.
