Hello,

Thank you very much for the very detailed explanation and examples! They
help a lot. I think I also want to make this a self-contained dialog and
manage keyboard focus to be trapped in the modal while it is open.

If mouse users are able to interact with content outside the modal (like
the header and footer), would that be considered inaccessible since it is
not the same experience? A keyboard user would have to close the dialog
before having access to the header/footer since keyboard focus would be
trapped within the self-contained dialog. It is indeed a different
experience with an extra step of closing the dialog to get to the
header/footer, but it seems to me that both experiences are accessible even
though they are different.

Thank you,
Kian Badie
