Because they are triggered from mouseover/mouseout events we end up sending these even when moving within elements inside the tab element.

It's not clear that there is any user-visible bug here but it is causing the
tab preview to get reset multiple times when that is unnecessary which at the
very least makes debugging harder than it needs to be.

This looks fixed to me using latest Nightly 126.0a1 on Windows 11 and Ubuntu 22.04, also I did a quick check on mac to see that no regression were introduced. Looks good. Closing as Verified since this will not launch in Beta 125 but 126.
