I'm having a hard time seeing an obvious culprit in that range :(
Hmm I can reproduce the problem on Win10 ESR52/ESR45 too.
(BTW, I can only reproduce problems on Google Chrome68 while/after the "save as" command is in progress.)
(OR, I can reproduce problems on Google Chrome68 when inspect the overplayed gray element.)
Looks like the div with class "media" is getting overlapped by the div with class "cd__content". Chrome will do the same thing after various actions (as noted above). To add to these scenarios, I Chrome do the same thing upon resizing the window.

I think this is in the layout/styling domain, am moving this to layout.
Component: Audio/Video: Playback → Layout
This problem can be reproduce on Chrome when the viewport area is resized, so I suppose they have some broken calculation code which gets triggered on Firefox somehow, but only triggered on Chrome when resized.
Priority: -- → P3
So the issue here is on the attribute `data-eq-state="xsmall small medium"`. With this attribute set on their ancestor, the .cd__content elements would match `[data-eq-state$="medium"] .cd__content` which uses `position: absolute; left: 0; bottom: 0;`, while without it, it would use just `position: relative;`.

On Firefox, this attribute is always set from the very beginning, while on Chrome, it is only set when resized.
