Steps to Reproduce: 1. Go to https://www.mediawiki.org/wiki/API:Alltransclusions 2. Insert a blank line after the first paragraph. 3. Use the Del key (not backspace) to delete that line. Rather than deleting the line, the first keypress (sometimes) does nothing. And then the second keypress finally gets rid of the newline, but attempting to save the page shows a diff with the newline still added.
Created attachment 12390 [details] Bug in Firefox 21 The described problem is slight different for me (Firefox 21) When inserting a new line and then deleting it, the paragraph is swapped with the next one. Although both paragraphs are still present on the visual editor, the edit diff shows that the first one has been removed.
This was fixed in the re-write of deletion handling in CE; sorry for not marking it as such beforehand.
