Hitting return mid-node copies contents instead of moving

to repro:

put your cursor in the middle of a node with some text
hit return
the contents after the cursor are copied to a new node below, but they also stay with the existing node. the contents should be moved to the new node, not copied.

@progrium - did you test this out...? now when i hit return mid-node it moves the text properly but it leaves an extra newline on the top node.

It goes away if I refresh the page. Tested in Chrome.

I did not test it with multiline nodes. The height calculation needs to be triggered.
