Loss of CSS when editing thread

Create a new style with no parent.

That will be a default style. Try it with that. You can delete it after testing.

If there is still a problem with the default style, it would suggest a server problem or add-on issue.
 
FWIW older versions of my Defer JS addon could cause this issue. Chrome's XSS auditor freaks out with deferred WYSIWYG editors and fails to load CSS or JS.

I believe I have your latest version, It was on Safari browser by the way, strange thing, did the same type of edit in a conversation and it worked fine.

Just tried it for the heck of it, and it did not seem to do it again, perhaps a server issue at the time.
