I'm not actually able to display some yari pages properly right now and I'm not sure why. The CSS and JS files are being served as HTML:

The stylesheet http://localhost:3000/static/css/main.debc7a6f.css was not loaded because its MIME type, “text/html”, is not “text/css”. Uncaught SyntaxError: expected expression, got '<'

[danielhjacobs]

Also worth noting, @queengooborg is making a concerted effort to remove all instances of true from the BCD, so this PR will only be useful for probably less than a month before that effort is finished.

There are 30 remaining files, all either webextensions.api or webextensions.manifest: https://github.com/search?q=repo%3Amdn%2Fbrowser-compat-data+%22%5C%22version_added%5C%22%3A+true%22&type=code (most were actually just updated, but some true values seem to have been missed).

Ah I see:

#4654

Unfortunately, many of the pages that reproduce this issue are there.

[danielhjacobs]

For reference, no files are left that are affected by this PR.

This PR is no longer be necessary, and https://github.com/mdn/yari/issues/11257 has been fixed by BCD updates. See https://github.com/openwebdocs/project/issues/206 and https://github.com/mdn/browser-compat-data/pull/24174.

As @danielhjacobs wrote, there are no occurrences of "Yes" left, so I'm closing this PR.

@gagan-bhullar-tech Thank you for taking the time to implement this change, and sorry we didn't get to land it. We appreciate your contribution!
