FWIW, dojo toolitp dialogs are an example of a popup dialog that traps 
the keyboard focus, where TAB keystrokes cycle within the dialog.  
However,  tooltip dialogs are not truly modal because if the user clicks 
outside of the dialog, then the dialog is closed.  A true modal dialog 
would beep in the case of outside clicks, and require the user to 
dismiss the dialog by choosing OK, Cancel, Close, or ESC.

Dojo uses role="alertdialog" here.  The spec for alertdialog suggest 
that authors SHOULD implement them as modal.  Dojo tooltip dialogs are 
"modal" with respect to the keyboard, but are not mouse-modal.

Also, part of the reason for using alertdialog is to cause an system 
alert event when the dialog pops open.

Here is the test page for dojo's tooltip dialog.  I don't vouch for its 
accessibility.  I might be accessible; it might not be:
