2027 Web Platform Feature Ranking

The most broken inconsistency across web browsers is printing, print preview, print-related CSS, etc. No print media related features made it onto this list :(

Some of these are pretty huge.

Responsive iframes been a long time coming.

Good to see.

Personally, I like the concept, but not the execution. It only changes its size externally on DOMContentLoaded, and again on load. So, if the user e.g. expands a <details> element, that won't update the size of the iframe. If the width of the main window changes size, resulting in the iframe changing width, resulting in the content within becoming a different height, it won't update the size of the iframe.

In cases like this, the iframe has to manually call window.requestResize(). And… that just doesn't feel like a big step up from the hacks we do today.

		I remember <iframe seamless> being proposed many many years ago. I wonder why that was rejected.

This needs to support category specific ranking. A feature like WebBiDi has nothing to do with the CSS engine team.

		Why does that matter? These are browser features in general for the upcoming interop-2027 The current interop has CSS features, WebRTC, WebTransport, IndexedDB, PWA stuff, etc: https://wpt.fyi/interop-2026

https://github.com/web-platform-tests/interop/. But… yeah, they should be on the site even before you log in. Let me fix that…

Fixed! Thanks for the suggestion. There was a whole read-only mode already there for when the process closes. I just didn't think of using it when the user is logged out.

You also need to know which resources I can access on GitHub. You don’t need that.

		This seems like bad wording on GitHub's part https://docs.github.com/en/apps/using-github-apps/authorizin... > When authorized, the GitHub App will be able to determine which resources you can access that the app can also access. The 'app' is used for login only. It has no access to resources.

How’s the gap decoration proposal coming along? Last update was the Edge post introducing it…

		It's shipped in Chromium only. It's one of the Interop 2027 proposals, so it's one of the choices in the list.
