add overflow:visible to allow the workspace action menu to be highlighted

[manutdkid77]

Description

On Mozilla Firefox, the uui-popover-container element would inherit a style of overflow:clip, this would hide the highlight of the Save/Publish menu on Firefox.

Setting overflow:visible to uui-popover-container allows the highlight of this element to be visible when tabbed into on Firefox browsers.

This fixes #16208
