Shockwave totem cannot interact with Earthquake support gems - Persistent Ground

In the description of Persistent Ground support gem: "Ground Surfaces created by Supported Skills cannot be destroyed except by expiring"

The bug here is that the jagged ground created by Earthquake cannot be erupted by Shockwave totem when persistent ground is equipped in Earthquake.

I think this is a bug because Shockwave totem doesn't destroy the jagged ground, the interaction between Shockwave totem and Earthquake is just Shockwave totem creating a new instance of damage via earthquake as you can see the jagged ground remained on the ground while the shockwave totem slam it, therefore the shockwave totem interaction shouldn't be counted as "destroying" the ground as the jagged ground is still present during this time period
