Viewing Diffs on MR page after 11.8.2 upgrade is very slow
Summary
After upgrading to 11.8.2 we have noticed that on a MR when you click on Changes, the loading spinner spins for several minutes and in some cases the diffs do not come up at all. However, if I click on a specific commit, the diffs come up right away.
Steps to reproduce
Navigate to a merge request. Click on Changes. Observe loading spinner spinning for several minutes before either loading the diffs or continuing endlessly.
What is the current bug behavior?
Diffs do not appear right away.
What is the expected correct behavior?
Diffs appear right away or within a few seconds of clicking on Changes.
