Comment (by afercia):

 Yeah, I was hesitant to address also the focus issue, because, ideally,
 that should work out of the box :( I've also quickly tried that and it
 triggers some weird behaviors:
 - in Firefox, the page scrolls and the editor area first line goes under
 the WP toolbar
 - in both Chrome and Firefox, if one line in the editor area was
 previously focused, clicking the label puts focus on that line because I
 guess CodeMirror remembers the previous insertion point; this behaviour is
 confusing when the focused line is outside of the visible editor area
 portion (which doesn't scroll)
