Possible leak in RefreshContainer where it doesn't stop a "Forever" composition animation

[Youssef1313]

Describe the bug

https://github.com/microsoft/microsoft-ui-xaml/blob/2a60e27c591846556fa9ec4d8f305afdf0f96dc1/controls/dev/PullToRefresh/RefreshVisualizer/RefreshVisualizer.cpp#L422-L444

This animation apparently never stops?

So, if many RefreshContainers are repeatedly added to visual tree, goes into interacting state, then removed from visual tree, those animations are likely to get stuck?

This shouldn't be a problem for a single RefreshContainer as the next interaction will cause another StartAnimation("RotationAngle", ..) which should stop the previous one.

Do you see an issue in the running app, or are you just noticing some suspect code?

[Youssef1313]

Just noticed suspicious code. The only way this can start causing issues is repeated interaction with different RefreshContainers. Each RefreshContainer will keep one animation running unnecessarily, if I understand correctly.

Once the RefreshContainer is removed from the tree and all references to it go away to RefreshContainer should get destroyed and so should the animation. So there should be no leak.

Are you seeing a leak of the RefreshContainer in this scenario?
