Suggestion

Currently the playground is pinned to the latest version.
It used to just use main, but we changed that as part of resolving #5939.
Unfortunately now it's not possible for us to test the playground against the latest code!

We should add a picker that lets us switch between latest, canary or any other "blessed" tags (eg rc-v6) so that we can test and show things as fixed in specific tags.

As an example - #6077 was fixed in #6059, but you can't see that in the playground:

I had to manually test locally to verify that it had indeed been fixed!
