The main use case I can think of for mixed editability is an image with a
caption. If anyone has other use-cases, that would be helpful in reasoning
about this. http://jsfiddle.net/UAJKe/
Looking at that, I think we should make it so that a selection can never
cross an editing boundary. So, in the image caption example, put your
cursor right before the uneditable div, then:
1. Right arrow should move your cursor into the caption text.
2. Shift+right arrow should select the whole uneditable div.
And delete/backspace can just be defined as extending the selection one
position and then removing the selected DOM. Relatedly, if you are at the
beginning of the caption text and hit backspace, nothing happens because
the backspace had nothing to select (i.e. selections are contained within
their first contentEditable=true ancestor).
As to the question of whether delete/backspace should select or remove
non-editable elements, I'm not opposed to giving this a try in Chromium and
seeing if users are confused by it, but I'm skeptical it will make sense to
people.
