In Persona: the animation in the content browser in the bottom right will play a preview animation when moused over.
These animations seem to continue to play on a loop even when you are no longer moused over them. This would be fine except the sound notifies attached to the anims also play which creates a very chaotic and annoying soundscape when trying to edit sound notifies on a different animation.
Additionally if I double click on Animation A in the bottom right Asset Browser in Persona to open the animation and work on it: the preview for Animation A continues to play even as I have that very same asset open in the main window.
The current workaround I am having to use is find an animation with no sound notifies on it, and mouse over it before I edit the actual animation I have selected. This is not fool-proof or ideal as switching between animations quickly will cause many many many notifies to trigger when quickly mousing over many animations.
Ideally these animations would not continue to play when not moused over or at the very least not have sound play when previewed.
