Overlay overlays all content
MultimediaViewer popup on mobile allows article content to "leak through".
The "pin" and label from the location map in the infobox is visible while MultimediaViewer popup is open. Article screenshot for comparison:
The same works correctly in desktop mode: https://pl.wikipedia.org/wiki/Kraków_Wisła#/media/Plik%3AWisla1.jpg, because the popup (<div class="mw-mmv-wrapper">) has z-index: 1001. These styles (and indeed this entire element) are missing on mobile.
We may have to bump z-indexOverlay and @z-indexOverOverla to extremely high number.
