Post Formats UI prevents switching back to the starting format

[georgeclaghorn]

Steps to reproduce:

1. Go to the Add New Post page. (wp-admin/post-new.php)
2. Change the Post Format from Standard to anything else.
3. Try to change back to the Post Format back to Standard.

Nothing happens. The UI refuses to change back to the Standard format. I'm using the 3.6 beta release of WordPress and the latest stable version of Google Chrome.

If you preset a different format for the Add New Post page (via the format GET parameter), and attempt to switch away from and back to the starting format, the results are similar.

Could not reproduce neither in Chrome 26 nor in Firefox 20.

Does it still happen on a clean install (with Twenty Thirteen theme activated and all plugins disabled)?

[georgeclaghorn]

Hmm, you're right. Can't reproduce on a clean install.

Would be nice to find the culprit and see what exactly causes the UI breakage.

This happens whenever I have the visual editor disabled. I'll look at the JS and see if I can find exactly where it fails.

Confirmed on a clean install with Visual editor disabled.
