Keyboard trap for non-modal dialogs and popups:

Dear members
I request for your inputs on the following thing.

Is it a good practice to trap the keyboard focus inside the popup or a
non-modal dialog?
I mean, while using arrow keys and tab/shift tab keys, trapping the
focus inside the popup.
Generally the mouse user is able to access the parent page and also
the popup simultaneously.
Should this be the case for the keyboard only users and screen reader users?
Which approach would be recommendable here?
What are the pros and cons for both the approaches?

Thanks for your inputs
Ramakrishnan
