compose: Fix using Up when editing messages. 

This fixes a very noticable regression in
92788a52bb, where using Up/PageUp/Home
when focus was in anything other than the compose box would
incorrectly be treated as message feed navigation.

Fix this by adding a new check, but this now has some fairly
duplicated code that queries the DOM for the same thing 3 times in a
row; added a TODO comment explaining a likely better approach.
