Summary Don't do async overflow scrolling for visibility:hidden scrollers

If a scroller has visibility:hidden, don't trigger the async overflow scroll code path. 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.
