Issue description

I create a normal zoom-in animation in the animationplayer. When I click the play button and hover the mouse over the button, the animation is obviously stuck. When I click the play button and move away quickly, there is no problem.And there is no problem using the A and D keys to play the animation.

Steps to reproduce

I don't know the reason for this bug, but FYI here's what I see when I play this video (a weird glitch):

glitch.mov

I am not sure if that was intended as I don't see any mention of this recording glitch in the issue.

I think what might be causing the issue is the tooltip, that shows when hovering over the play button. I've seen tooltips cause weird rendering artifacts before in Godot (but in Compatibility, not Forward+).

@hypiuser Does the bug also happen if you first wait for tooltip to show, and only then play the animation?

Please provide an MRP to make this easier to test and fix:

• A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the .godot folder in the archive (but keep project.godot).
• Having an MRP is very important for contributors to be able to reproduce the bug in the same way that you are experiencing it. When testing a potential fix for the issue, contributors will use the MRP to validate that the fix is working as intended.
• Drag and drop a ZIP archive to upload it (max 10 MB). Do not select another field until the project is done uploading.
• Note for C# users: If your issue is not C#-specific, please upload a minimal reproduction project written in GDScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a .NET setup available.
