fix(material/tooltip): animation not cancelled when mouseleave goes through tooltip (#25740)

We ignore `mouseleave` events that go into the tooltip which meant that some animations weren't being cancelled correctly after the fix in #25699. These changes resolve the issue by skipping all animations if the tooltip isn't fully shown yet.

Fixes #24614.

(cherry picked from commit 6526277)
