Security researcher Zach Hoffman reported that a recursive call to eval() wrapped in a try/catch statement places the browser into a inconsistent state. Any dialog box opened in this state is displayed without text and with non-functioning buttons. Closing the window causes the dialog to evaluate to true. An attacker could use this issue to force a user into accepting any dialog, such as one granting elevated privileges to the page presenting the dialog.
