Created attachment 50728 [details] Example of position:relative flash on animation Upon the animation of another element, a z-indexed, text-indented, position:relative element flashes. The original flashing element was a page header with an image background (the text-indent kept the text outside the element). There are several minor elements that must be in place for this quirk to surface. In the attached example, hover over the "hover me" element to see the flash.
This might be some past style invalidation bug which I am not able to reproduce this in Safari 16 and other browsers (Chrome Canary 108, Firefox Nightly 107). I am marking this as "RESOLVED CONFIG. CHANGED". Thanks!
