Why does the preview window of any tab sometimes move to the upper-left corner?

If I have several tabs open and I quickly hover over them, the tab preview window will move to the upper-left corner.

On Linux (Wayland) systems, certain popups and context menus will sometimes open in the wrong place, such as the top-left corner of the window. Firefox 147.0.3 has a partial mitigation for this problem and remaining instances will be addressed in a future release. (Bug 2003045)
