oh no worries@josepharhar that was a note for me, not so much for you.

if you did want to take it on, we'd need a new button as a child of a select entry in the table - using a similar ID like I'm setting up over in html aamel-button-select-child

but really, don't worry about it. i was planning on working on finishing this PR once the HTML/HTML AAM PRs were a bit closer to done.

latest commit updates selectedcontent to align with recent HTML AAM changes.

also added in the button as a child of select variant / expectations.

test case file created and added to OP -https://w3c.github.io/html-aria/tests/selectedcontent.html

discussed with@scottaohara separately. we're ok with the current wording, as the specifics of what a "valid descendant of aselect" is are defined already in HTML, so we can keep it snappy. merging.
