Bug 249279

Hi Team,

While going through Blink's commit, I came across another paint invalidation bug:

Test Case (don't run in full screen, run in JSFiddle and watch result window/section) - https://jsfiddle.net/2Lpoj4tv/

^ In Safari 16.2 & Safari Technology Preview 159, the box show slim layout skeleton and then the box move while in other browsers like Chrome Canary 110 and Firefox Nightly 110, there is no as such artifact or glitch where a layout is showing where the box is going to move. It does not happens after multiple runs and also on first try sometime the box does not move at all as well in Safari.
