Use the JSX of the ViewTransition as the Stack Trace of "Animating" Traces (facebook#34539)

Stacked on facebook#34538.

Track the Task of the first ViewTransition that we detected as
animating. Use this as the Task as "Starting Animation", "Animating"
etc. That way you can see which ViewTransition spawned the Animation.
Although it's likely to be multiple.
