This code should go in commitPassiveMountOnFiber

I don't think this is the right flag. I would use Passive instead.

Also please leave a comment explaining why this flag is being set. It's not obvious from context.

Does passive work here? We would want to know when to run the transition tracing specific code somehow right (ie. when a suspense boundary toggles). If passive is set it doesn't necessarily mean that the suspense boundary has toggled.

We only want to schedule an effect if there was actually a new transition. This will schedule an effect even if nothing changed.

If a suspense boundary toggles in visibility, we should also schedule a passive effect even if there are no new transitions because this might mean we completed the interaction (or the pending boundaries array changes at least)

Ok makes sense, thanks for the added inline comment!

This PR moves the code for transition tracing in the mutation phase that adds transitions to the pending callbacks object (to be called sometime later after paint) from the mutation to the passive phase. Things to think about: Passive effects can be flushed before or after paint. How do we make sure that we get the correct end time for the interaction?
