a.html

It depends what the next sibling element contains when a Delete key is pressed in an empty DIV, while I'd expect the same behaviour (the empty paragraph being removed) regardless of the next element content.

a) Open the attached a.html file in a MiniBrowser like this:

     $ MiniBrowser --editor-mode /tmp/a.html

   It opens with this content:

      line 0

      > line 1
      > line 2
      > line 3

   where the '>' are orange.

b) Place the cursor on the second line, aka on the empty line below the line with the 'line 0' text.
c) press Delete key

What happens:

The text is changed to:

      line 0
      line 1
      > line 2
      > line 3

What is expected:

Only the empty line is removed, thus it might look like this:

      line 0
      > line 1
      > line 2
      > line 3

Note: It seems to be related to -webkit-user-select: none; style property of .-x-evo-quoted (see the a.html file). When I change the ".-x-evo-quoted" in the <style> to something else, thus it doesn't match anything in the HTML body, like to .zzz-x-evo-quoted, then the steps behave as expected.

I see this behaviour with WebKitGTK+ at r258908.
