I’m not able to change the spot where the Insert Object panel is docked, with a few exceptions. It seems I can change its docking position as long as it stays on the same side of the screen. I can pop it out and it’ll act normally, but when I try to dock it back it just jumps back to where it was previously docked. I changed my layout to test this and now I can’t change it back.
It’s hard to describe the wonky behavior, so I recorded a clip of it happening:
I’ve only just noticed this recently, but it’s probably been a thing since the widget was refreshed.
