Colour pop up window hangs on home tab

v1.3 beta6 on win10

i usually summon colour pop up bar with F4 and drag it around, having it open all the time. when i switch to home tab it won’t dissapear and gets stuck in its place. it can’t be closed or interacted with. you have to switch from home tab to another one and hide it.

on the other hand, if colour pop up window is hidden and you switch to home tab, you can open it with shortcut and the window behaves normally - the colour can be changed, it can be dragged around and closed.

i believe switching to home tab should hide this window just like for example preview window and user shouldn’t be allowed to open it with shortcut.
