Skills automatically repeating

Have had this issue on multiple characters now across the last few weeks. Skills in the left two positions will periodically start repeating infinitely upon a single activation of the assigned key, allowing interruption from activating other position skills or moving, but preventing clicking on boxes, strongboxes, essences, or picking up items. I can stop the repeating by removing the gem from the socket or clicking something outside of the game.

I have rebooted my PC multiple times since first encountering this problem, and have repeated the same issue.

So far I have noticed this with the following:
1. non-cooldown totems: shockwave totem, ancestral protector, and ancestral warchief, but not decoy totem
2. both splitting steel and call of steel
3. double strike
4. split arrow
5. default attack and Move Only
6. Tornado shot
7. Corrupting Fever, Anomalous Corrupting Fever
8. Flame Dash
9. Molten Shell
10. Earthquake
11. Cyclone (stays on as if continuously channeling)
Vulnerability, Ground Slam, Heavy Strike, Temporal Chains, Spectral Throw, Frost Blades, Penance Brand, Wave of Conviction, Soul Rend, Cold Snap (on cooldown)

It does not toggle auras on and off

If I activate a skill in this way, and it starts repeating, then assign a new skill to that key, and activate that skill, the new skill will take over repeating. Then if I remove the second skill from it's socket, the first skill will resume it's repeat pattern.

If I assign different keys to those two skill bar positions, it seems to fix it for a while, but I don't see rhyme or reason as to how long that fix will last.

The behavior is not affected by changing from Razer Tartarus game pad (or having the game pad unplugged entirely) or different keyboards.

The behavior persists in acts, maps, delve, lab, menagerie, and hideout (did not try tane's lab, logbook, or heist)

Edit - now I've seen it do the same thing with cooldown totem: decoy totem, and it's done it on middle skill slot now, but still usually left 2 slots
