Creative Commons HTML breaks editor

[ThomWright]

Symptoms

On affected page:

• no preview
• when trying to change file from the 'Files Tree' the hash in the URL changes but the UI doesn't respond

Cause

As far as I can tell, the following HTML, generated from Creative Commons, seems to be the problem. All other files in my repo seem to be fine.

Update
Having something like the following also breaks:

<div align="center">This is some text!</div>

but having a simple div seems fine:

<div>This is some text!</div>

It should be fixed in the latest release.

Thanks! I had to take the CC stuff out of my build. Testing it now.
