PageSpeed Insights - Accessibility (ARIA)

Problem/Motivation

Hello, I'm using the FAQ field module on my websites and it's really nice.

I render them with the JQuery accordion formatter.

I've noticed that PageSpeed Insights has accessibility warnings based on the standard implementation.

Steps to reproduce

Setup a FAQ field with formatter JQuery accordion.

Run the PageSpeed Insights tool (https://pagespeed.web.dev/).

You'll see you get a 95 score (if your websites complies on all other points and a notice):

"Elements with an ARIA [role] that require children to contain a specific [role] are missing some or all of those required children."

I've already changed the h3 to a button to see if that helps and some other stuff but I keep getting the warning.

Anyone else has any ideas? Would love to get this fixed.
