[BUG] Some PR completely break layout

[paveldudka]

Describe the bug
Some PRs upon navigating to them in gh dash break layout - top sections bar disappears and all further navigation is completely messed up.
In the video attached, at the 5 seconds mark I navigate to PR titled "chore(deps): update".
At this point top section bar disappears and after that I don't really know how to describe UI behavior. In the video Im just pressing up/down arrow keys.

I can only repro it when "preview" panel is open. If I close preview panel - it works fine

To Reproduce
I don't know what part of the offending PR causes this, so its hard to provide repro steps

Expected behavior
UI is not broken
