Comment:

 First pass. The JavaScript part may need some optimization, as mentioned
 above. In the screenshot below, the NVDA Speech Viewer showing how the
 dialog content gets read out with the patch applied. Notice:
 - users are now informed they're in a "dialog"
 - initial focus goes to the current Tab
 - switching tabs with arrow keys announce them correctly as "1 of 2" and
 "2 of 2"
 - when the input and textarea get focus, their descriptions get read out
 - tabbing is constrained within the dialog
