FYI: The assistive technology I'm using doesn't recognize it as a button, nor does it seem to even have a tabindex.
If you can get in touch with the frontend person, please recommend that they use a link (A element) or button (INPUT element) to make the control, otherwise it is not recognized as clickable by some useragents.
Thank you for this. Will make sure this is addressed asap. We previously far overused divs (and still do) and have been going over everything making them buttons but still need to do a lot of work in making it more accessible.
