Component state should be frozen when outro is playing

[ToP29]

Describe the bug

I have Breadcrumbs component, which updates based on breadcrumbs store. Store updates when +layout.svelte gets mounted or destroyed.

Problem is that breadcrumbs gets updated when outro animation starts, so user sees new bradcrumbs on old page. I think that outgoing component should have its state frozen, so it can not update while animation out. Or there should be at least option to enable this behavior (possibly param in transition function)

This could also fix this issue: Store updates break transitions and components #3685 which is wrongfully closed.
