Can be tested with the built-in accessibility check of Firefox developer tools. Before applying the PR there are also errors about missing labels, after applying the PR only a contrast issue is remaining. Markup inspection looks right, too. The "for" of the labels fits to the IDs of the selects.

P.S.: Testing sample data can be used on a development version to get the archived article and the menu item. It just needs to set the filter to be shown as described in the instructions.
