This is a recent regression. Steps to reproduce: 1. Open many tabs so that tab strip will over flow. 2. Mouse hover over a tab so that tab tooltip will pop up. 3. Rotate mouse wheel to scroll tabstrip. (don't move mouse position) Actual Results: The tab tooltip will remain visible. After scrolling, as a result, the content of the tooltip becomes unrelated to the tab at the mouse pointer position. Expected Results: Like Firefox87.0b4, tab tooltip should be hidden when scrolling tabstrip.
