I believe bz's theory is that the <browser>'s binding was being force-applied because the <browser> was being wrapped to be passed to your JS-implemented content policy (as aContext). XBL bindings are force-applied when an element in a document is JS-wrapped and its binding hasn't yet been applied through normal mechanisms (i.e. layout).
