[Painterro] Painterro text input not being removed after annotating Snapshot

[charlesh88]

Seen on /stable 1.7.5 and current master running locally.

Reproduce

1. Create a new Snapshot, click it and get to the annotation interface.
2. Add a text element:

3. Save the annotation and exit the Snapshot overlay dialog. Note at the very bottom of the tree on the left you'll see a pink dotted line:

4. Dragging on the browser's bottom edge to Increase the height of the window will reveal the annotation's text element:

5. Looking in Dev Tools > Elements, you'll see that contenteditable divs are being left in the DOM:

Multiple rounds of annotation leave multiple contenteditables remaining; refreshing clears them. Although the above screenshot shows a count of two console errors, they aren't being created by this problem.
