In TB 78, getAnonymousElementByAttribute() is no longer supported, and we throw an exception trying to obtain the displayed message's subject. We may also be failing to obtain it in TB 68; and - we may be failing to set it, once the charset changes, using our setter function.
Let's try to rewrite that piece of code in the messenger onLoad() handler to properly support what works in TB 68 and 78.
