23478 2013-10-10 05:23:25 +0000 <dialog>: The "Submit dialog" steps can't run the exact steps for closing a dialog, since no exception can be thrown 2013-12-11 21:36:20 +0000 1 1 1 Unclassified WHATWG HTML unspecified PC Linux RESOLVED FIXED P2 normal Unsorted 1 falken ian ian mike contributor oldest_to_newest 94541 0 falken 2013-10-10 05:23:25 +0000 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.
