BUG: Unearth on left-mouse prevents looting in combat (Even with loot key!)

1. Bind Unearth to left mouse button
2. Set "Game -> Key Pickup" to "Use Highlight Key"
3. Set the highlight key (F) or use default (Alt)
4. Fight some enemies until loot drops (and bodies are on the ground)
5. While in combat, try to hold your highlight key and loot a text-label

WITNESS: it casts unearth instead of looting, EVEN THOUGH i'm holding my loot-key down

It seems like this is some kind of "feature" to prioritize Unearthing bodies during combat instead of looting labels.... but it should NOT happen when I'm explicitly using and holding a loot key.
