Description Matt Falkenhagen 2013-10-10 05:23:25 UTC 
The steps for "Submit dialog"[0] involve running the steps to "close the dialog"[1], which require throwing an exception if the dialog does not have an 'open' attribute. However, it's not possible to throw an exception here, since there is no JavaScript running.

It's possible for the dialog to not have an 'open' attribute at this point, if for example dialog.style.display was set to 'block' while the dialog was closed.
