If you do 'Edit Page', the resulting page in editor has a number of problems: 1. Sometimes, content is duplicated 2. Part of all of the page is not editable.

These problems go away if you turn off the timer-based content notifications with the pref user_pref("content.notify.ontimer", false);

Mmm, this problem does not seem to occur when loading the page through a file: (or chrome:) URL, only http. Even the simplest page with at least one tag in the body will show the problem.

More info: the content model looks good, so the problem is in content -> frame construction.

This looks very much like it's caused by bug 21459. What's happening is that the OnEndDocumentLoad is being called too early, so the editor gets instantiated before the document is fully reflowed. Because of this, the editor is making the bogus <BR> node, which confuses the content sink and causes teh doubled content.

Good, rick's fix for 21459 fixed this too.
