Some JS libraries make visibility:hidden scrollers (https://github.com/wnr/element-resize-detector) and we need to avoid the compositing cost. I filed https://github.com/w3c/csswg-drafts/issues/4113 on this not being well-defined in CSS, and expect that to be resolved in a way that prevents scrolling. 1552708 1 webkit-bug-importer 2019-07-13
