JAWS announces all the contents of modal dialog

Issue Summary

JAWS announces all the contents of "create Issue" modal dialog automatically.

Steps to Reproduce

1. Turn on JAWS & Navigate to Jira.
2. Navigate to "Create" button in header & activate it.
3. Press tab until you reach "Configure fields" button
4. Observe that JAWS starts reading all the contents of dialog automatically.

Actual Results

While navigation with JAWS, when user press tab to navigate to elements such as "Configure fields", "show/hide toolbar", "description" field, etc JAWS starts announcing all the contents of modal dialog automatically.

This creates a bad user experience for JAWS users.

Note: this issue seems to be applicable on all the toolbars in Jira & elements which are wrapped inside a role=toolbar element.

Expected Results

When user press tab to navigate JAWS should not announce all the contents automatically, instead only the currently focused element should be announced.

Workaround

1. Press ctrl and the speech will stop. You can press JAWS+tab to verify focus.
2. Turn off the virtual pc cursor and this doesn't repro.
