问题
The confirmation dialogues in chrome are not accessible to JAWS screenreader (Version 18.0.2945). I experienced that with a simple onbeforeUnload dialog as well as with a javascript confirm dialog. The text in the dialog will not be read. Did anyone experience similar problems or knows an answer?

As of today, 18/09/2017, this is a jaws issue. The code works on all other major browsers. There is no solution at present.
Just for your information, alert and prompt have the same problem. HTTP basic authentication dialogs aren't usable either. Everything works with NVDA.
Freedom scientific, please, fix this issue.
