The glitch should be gone now.

FYI: #7548 is a different problem.

The PR looks good to me and I'd be completely fine to merge it but what I described in #7548 (comment) worries me. Why two similar issues appeared so close one another? What's causing the paste/upload glitch? I have a feeling that there's something wrong elsewhere and that a fix for that thing may fix both issues.

Still, I'll be ok with merging this PR, but after we check whether a fix for the other bug will not resolve this too (if we merge this PR it won't be that easy to check).

I couldn't reproduce the upload/paste glitch and I asked the issue author for more details. 

In the meantime, this PR addresses not only the resizer glitch issue but also fixes the nasty View#render() loop when an image is selected, which could have other unidentified consequences in the editor.
