Suggestion

Coming over from #6350: we had an issue with our React code caused by us using invalid HTML. Specifically, React was logging this:

Warning: validateDOMNesting(...): <div> cannot appear as a descendant of <p>.

We should end-to-end test to make sure this doesn't happen on the homepage again. Right now we just test that the homepage has no accessibility issues detectable by aXe:

Playwright is able to listen to console messages. I propose we make a second end-to-end test that checks to make sure no console.error calls happened.

It wouldn't surprise me if a library already exists for Playwright somewhere that does this...
