Map element popup corrupted, cannot edit links

When editing a map, both the popup for a single element, and multiple elements, have their action buttons in the wrong place. Whether because of this or something else, the links section at the bottom cannot be selected, making it impossible to edit link names in the map. You can create a link, but not change its name or conditions.

I've tried this in Chrome and Firefox (current). Even though you can see the edit link, I cannot get it to activate at all.

I see some items are being closed generally to duplicate ZBXNEXT-2662; please indicate if you would prefer these types as comments in that one?
