Broken: version: 2.83.3, branch: master, commit date: 2020-07-22 06:01, hash: 353e5bd749, latest 2.90, 2.79b
Worked: never

Short description of error
Using a bunch of image editor panels in the layout workspace for reference, for example, and switching to the texture paint tab for texture correction on an object changes the displayed images to the one from the texture paint tab, which brakes your workspace setup. I deliberately made four panels to show you the tediousness of the re-setuping each time you want to paint some textures.
It only occurs with a texture assigned to an object in the shader. If you delete the image node in the monkey's shader, the problem is gone, but there's no point in going to texture paint then :)
This was a long lasting inconvenience, which we can fix now at last. I render it as a bug now, as it really brakes your scene setup.

Exact steps for others to reproduce the error

Open the attached file. You'll see four panels with a motorcycle
Switch to the texture paint tab. You'll see a hexagonal texture assigned to the monkey to paint
Switch back to the layout tab and all four panels are now having that hexagonal texture, and you have to select the previous lovely motorcycle image once again. Imagine you have 10 panels with 10 different images.
