System Information:
Operating system: Linux
Graphics card: GTX 1050ti

Blender Version:
Broken: 2.82a release, 2.83 (133bf05b18 - 2020-04-27 19:14), 2.90 (fd0cb58122 - 2020-04-27 19:15)
Worked: Unsure

Short description of error:
In the image editor you can view your render result. While viewing your render results you can view different slots. And in each slot you can view different render passes. Let's name the render passes in numerical order for simplicity. Lets assume the render in slot 1 has 3 render passes and the render in slot 2 has 4. If you select the 4th render pass in slot two then switch back to slot 1, you will not be able to select which render pass you wish to preview. But if you select a render pass in slot 2 that's within the first 3 in the list, matching the total number of render passes in slot 1, you will be able to select which render pass you wish to view in slot 1.

I'm having a hard time explaining it, so here's a video:

Exact steps for others to reproduce the error:

Take any scene and render out a image.
In the image editor with the "Render result" selected change to slot 2.
Add a render pass to your render.
Render out that image.
Change your render pass in slot 2 to the last render pass in the list.
Switch back to slot 1 and notice that the ability to chose which render pass you see is gone.

This issue will occur for every render pass you select that's from a spot lower down in the render pass list than other renders in other slots.
