I expect this is due the "tabbox" property being set in the TabBrowser constructor directly rather than lazily. Alas, just accessing DOM node like this invokes XBL.
Like in bug 1444218 and in bug 1444183, the fix hadn't merged in yet when this occurrence hit. Please provide links to cases where this is orange *after* the fix from bug 1443318 merged if filing again.
