Regressed by:
79c73def3bdf45398212e2cd53137667098d560f	 Stone Shih — Bug 1392876 - Enable coalescing mouse events to be once per refresh cycle (enable the pref). r=smaug.


And I confirmed that setting dom.event.coalesce_mouse_move = false fixes the issue on Nightly75.0a1 Windows10.
So, Stylo hides the existing issue.
