Comment drafts on merge requests are lost when scrolling

Summary

When you are drafting a comment on a merge request and scroll to a certain depth, the text which you have written into the comment box disappears. This causes you to lose your work.

Steps to reproduce

1. Go to !134003 (diffs)
2. Begin writing a comment on a line inside the first file
3. Scroll down to the very bottom of the diff (note: This was reproduced displaying multiple files at a time)
4. Scroll back up to the first file
5. The text which you had written in the comment box is now gone
