The Attribution on the displayed Google Maps disappears above the map overlow if the theme defaults DIV elements globally to position: relative, triggering a Violation directly from Google to fix the attribution. In order to fix, I have to add something like:
.wpgmza_map > div > div.gm-style div:last-child { position: static; }
This is something the plugin should consider, so that people aren’t suprisingly violating the TOS. TBH, I had no it was hidden until I was sent a non-compliance email.
