Can't restore brush if picked up with Magic Wand

I think it's a bug...

  1. Use Magic Wand Pick up to create a brush.

  2. Reset brush to single dot with period key.

  3. Brush>Restore

I expect this to bring back the brush I picked up with Magic Wand Pick up tool, but it does not.
It either does nothing, or my brush is changed back to what I had picked up with a different pick-up tool.

It’s as if brushes picked up with the Magic Wand Pick up tool aren’t remembered as brushes - PMNG “forgets” about them.

I consider brushes created with the Magic Wand Pick up tool the same as any other brush. How a brush is picked up shouldn’t matter, right?
Brush>Restore should always revert back to your previous non-round/square brush, I believe.
