Screenshot of the bug
The diff in the save dialog isn't being styled correctly, which causes highlighted text to overlap with text above it. Timo tells me that this is due to a missing line-height style.
This is exacerbated by bug 60494. which causes the save dialog to be narrower than it should be, which means lines wrap more often and highlighted text more frequently has text directly above it.
