[Bug] UI Elements Non-Interactable

The mount (Z) and hearthstone (B) buttons on the bottom UI have been non-interactable for quite some time. What I mean by that is that they do not display tooltips when moused over in game and they cannot be clicked. The most immediate consequence of this is that it is currently impossible to announce the cooldown of certain mount abilities like Falstad’s Fly, Deathwing’s Dragonflight, Dehaka’s Burrow, Sgt. Hammer’s Thrusters, Brightwing’s Phase Shift by alt-left clicking them.

This may have started with the switch to the Metal rendering engine, which did cause a lot of UI bugs the first time it was implemented, but I’m not really sure since it only matters very infrequently during gameplay.

I’m running the current version of Heroes on macOS 10.14.6 (18G9028) on a MacBook Pro (15-inch, 2018) with a 2.9 GHz Intel Core i9 and a Radeon Pro 560X 4 GB.
