Created attachment 97679 [details] Test Case window.getComputedStyle() doesn't seem to work for pseudo elements until unload. It seems like the style is not available until it has been painted. Test case attached.

This is probably what the comment in Element::computedStyle is referring to when it states: // FIXME: Find and use the renderer from the pseudo element instead of the actual element so that the 'length' // properties, which are only known by the renderer because it did the layout, will be correct and so that the // values returned for the ":selection" pseudo-element will be correct.

Created attachment 97680 [details] [WIP] Patch This patch fixes the issue, but I am not sure it is the best the way to do it. I am also not certain what should be done about the case of the element not in the tree/with no renderer.

With attached test case, I am getting this across all browsers (Safari Technology Preview 160, Chrome Canary 111 and Firefox Nightly 110): In Script: rgb(0, 0, 0) On Load: rgb(0, 0, 0) On 100ms Timeout: rgb(0, 0, 0) Button Clicked: rgb(0, 0, 0) Is this still an issue? Thanks!

Seems like this was resolved indeed. The FIXME is also no longer present.
