Description
Just want to quickly drop mention as I happened to run into it tonight: the language picker (JS/TS) associated with most code snippets is missing the required accessibility props to tie a particular tab with a tabpanel. At a minimum, each tab should have aria-controls set w/ the ID of the corresponding tabpanel and you'll probably also want to add aria-labelledby to the tabpanel pointing back at the corresponding tab. Without this information, it's quite difficult for non-sighted users to discern the relationships between particular tabs and tabpanels.
MDN has a very comprehensive example going over this, should be a quick & easy fix. Took quick peek myself but couldn't find where you were creating these components -- maybe it's a Docusaurus thing? Not sure.
