Random switching between panes #6160

Describe the bug

When you try to diff anything, searching through branches or anything else, it could randomly switch from your diff -> out of diff -> select reflog pane. Same could happen in branch view, it could switch you out from diff/remote branches -> commit pane -> reflog or something.

Everything is done in a split second.
I don't have a mouse4/mouse5 buttons physically, nor do I have some kind of macro or anything.
My layout is default one.

This happens randomly, especially this issue can occur 5 times in a row while trying to review.
I could not reproduce it with --debug run.

To Reproduce

Steps to reproduce the behavior:

Try diffing a large commit(s) in ether Branches or Commits panes

1. Switch to Commit pane
2. Enter commit or select multiple commits and press Enter
3. (I would Shift + > to the bottom most file first, but it don't seem to matter)
4. Just browsing files, checking them (Focus is not required, it can happen without it)
5. If you are lucky enough it will randomly switch panes

Also you can get it while scrolling through selected files in Files pane, it then could switch to the submodules pane randomly.

Expected behavior

Nothing should switch me between panes unless I use Arrow Keys/Mouse clicks.
