Re: Meaningful Sequende Question

Hi All,

Does anyone have a list of browsers and versions that correctly parse
aria-modal="true" so that the user's Tab sequence is properly constrained
within the container marked up with aria-modal="true" with no additional
custom focus management?

The reason why I ask has everything to do with user outcomes. I understand
that SC 1.3.2 Meaningful Sequence in WCAG 2.x is passed if the Tab sequence
"can be programmatically determined." But just because it "can" doesn't
mean that the proper Tab sequence "will" be set if the browser/user agent
doesn't render the modal content using the content author's intended
interaction pattern.

Do content authors have any assurance that if they use the right page code
to pass SC 1.3.2 the Tab sequence will achieve an accessible result for
users with disabilities who use a keyboard or similar input approach?
