I can't say how long your mouse need to be over the button. But it seems that it's just a tad less than it takes the tooltip to appear. However, I stumbled upon this at least twice doing other things and can reproduce quite reliably.

There seems to be some race condition.

✔️ Expected result

The tooltip doesn't show up / hides.

❌ Actual result

The tooltip stays visible until the next mousein&out.
