1) Go to http://www.mediawiki.org/wiki/Special:VisualEditorSandbox with Firefox 2) Put your cursor anywhere in the text 3) Press CTRL-A (or select all text with the mouse) 4) Press "Backspace". All content disappears. 5) Type "a". 6) Press "Backspace". Problem: "a" is not removed.
Confirmed on Mac/Firefox too (no issue on Chrome, Safari)
Now fixed in master.
Assigning this to a release milestone so it's clear when at the latest to expect it to have been fixed; it may have been fixed beforehand.
