New test to ensure in-validness of el.ariaLabeledBy and el.ariaLabeledByElements… Misspelled content attribute aria-labeledby is an author error but supported by the engines and tested in WPT... but the misspelled DOM properties should not be supported.

From: https://github.com/w3c/aria/issues/2093#issuecomment-2698480966

We should probably add another test to make sure [the misspelled aria-labeledby doesn't] accidentally get a new DOM interface though. E.g. el.ariaLabeledBy and el.ariaLabeledByElements should not get any new behavior.

There are objections to enshrining the misspelled content attribute, so this one may be closed as Not To Be Fixed.
