(Whiteboard: [webcompat:p3] [css])
This is a spin-off of a webcompat issue. https://webcompat.com/issues/10088 The behavior is strange. This is happening on a high profile Web site, aka reddit on mobile Android only. Steps to reproduce: 1. Go to reddit 2. Login 3. Click on the top reddit button to expand the menu 4. Click on the subscribed topics (You need enough topic that it is taller than the viewport) 5. Try scrolling the list. It doesn't scroll in Firefox Android. It does scroll on Firefox Desktop RDM with firefox Android UA. It does scroll on Safari/Chrome on Mobile. When modifying a bit the css to be able to see the menu and the content behind, if we try to scroll the menu, we realize that the background main content is flickering, like if the scroll was partially attempting to happen on the content behind. Once we hide the content behind, we can scroll easily. See full details in https://webcompat.com/issues/10088

Did we get a reduced testcase for this? Or a testcase? Is this still happening?
