Jan KassensandRick Hanlon d3d4d3a46b Call cleanup of insertion effects when hidden (#30954)
Insertion effects do not unmount when a subtree is removed while
offscreen.

Current behavior for an insertion effect is if the component goes

- *visible -> removed:* calls insertion effect cleanup
- *visible -> offscreen -> removed:* insertion effect cleanup is never
called

This makes it so we always call insertion effect cleanup when removing
the component.

Likely also fixes https://github.com/facebook/react/issues/26670
