Earthquake - Jagged Ground Never Expires

Though I have had this happen several times, I've most recently encountered it in the Snake Queen boss fight in Keth, Act 2

Sometimes Jagged Ground produced by Earthquake does not expire and explode into an Aftershock. The Jagged Ground stays permanently on the floor - This prevents further Aftershocks from EVER triggering once the maximum number of Jagged Grounds are permanently stuck in place.

Removing the skill gem from the character and placing it back on while in the zone did not remove the Jagged Ground or cause it to expire.

It is incredibly detrimental to the Earthquake skill. Small arenas can eventually become just you standing there using your default attack. In an already quite particular slam-based play style---very awkward to use as you cannot stack attacks on one spot. (And auto-aim renders this even more difficult to trigger consistently, even without the bug appearing.) This renders the skill unusable after a while.

I presume since this is an instance/zone effect which does not go away, the only work around would be to step into or produce a new instance of the zone where the skill has become disabled. As soon as I went into the Lost City zone from Keth, testing in the door, I was able to Aftershock as intended.
