Comments intermediate state
We should have an intermediate state in comments, where something has been written, but not submitted.
This should keep the comment active, even if the selection goes away from the annotation.
If the page is reloaded, non-submitted comments are lost.
This should work in a similar fashion to google docs comments, for a UI reference.
Some changes are needed in the way we handle comments to enable this.
Off the top of my head, we should allow for multiple active comments, but I'm sure more will come up.
