Void Sphere / Void Sphere of rending - Of rending inherits cooldown of void sphere (video added)

I am reporting a bug where, if you socket void sphere into a slot, and then swap it with a void sphere of rending, the void sphere of rending will inherit the cooldown of the regular void sphere (For context, the "of rending" version has no cooldown.) The cooldown disappears if you switch the "of rending" gem to a different socket - the cooldown inheritance bug seems to only apply when put into the same socket.

But this also makes me wonder if there are deeper reaching implications for transfigured gems and their non-transfigured counterparts.

I displayed the bug in action on this video
