Stop automatically exposing details relation for figure -> figcaption

[aleventhal]

I thought we had filed this, so there may be a dupe somewhere.
We should stop automatically exposing the details relation between figure and figcaption. They are nearby in the DOM anyway. It was so noisy on some pages that it caused JAWS to stop reading details relation entirely.

@aleventhal maybe you're thinking of w3c/aria#2224 ?

Thanks @pkra . I mentioned it in a comment in that PR. But it hasn't been changed in that PR. Should we keep it as a separate issue? Or do you want to add to that PR?

i was planning on handling it in the PR - i've just not had the time. someone else can update the PR, otherwise it's on me to get it done - and i will as soon as i can.

i have updated the PR

@aleventhal to be fair though, since the PR never landed because we've been waiting on other browser to implement, chromium should be fine to remove it even without the PR update.

let's keep this issue open so it can come up in triage - and then this can be a reminder for people to re-review the PR so we can get it merged asap
