I've made the modals more a11y friendly with this commit.
When modal opens, focus is forced to the modal itself
When the modal closes, focus is returned to the calling element (usually the 'Add' or 'Edit' button).
Modals now have aria-labelledby tags to announce them on open, and aria-hidden tags to hide them from the screen reader when not active
Presses of the TAB key are intercepted and forced to only cycle through items within the active modal
Presses of the ESC key are intercepted and now close the modal
Hope that helps.
