Bug - Essence Drain Locks Movement

Hello Legends at GGG,
So small bug with ED where is locks my characters movment if I hold down the key that casts it. Using it on left mouse click and character will cast ED as long as I am holding but is unable to move as it appears to 'step' me back to where the animation started.
Below is a clip I captured that I hope will explain this better.
