[howard-e]

Hello, reviewers! As of 2025-12-05, the wpt-pr-bot is requesting reviews from code owners for changes to WEB_FEATURES.yml files. To learn more about the purpose of these files, check out this presentation from TPAC 2025, Annotating WPT to Surface the Status of the Platform.

Feature: "@font-face"
Reference: https://github.com/web-platform-dx/web-features/blob/main/features/font-face.yml

Notable exclusions:

• css/css-fonts/test_datafont_same_origin.html, testing font-face and font-family

This mostly looks good, but I have questions about 2 of the mappings.

[dbaron]

Is the idea of the feature mapping that we map each test to a single feature, or potentially multiple features? These tests are primarily targeting the WOFF font format, so I'd probably be inclined not to call them font-face tests unless we also call them WOFF tests.

The idea is to map to a single feature and going back over this, I agree.

I think these first-available-font-* tests also aren't primarily targeting the font-face feature. (see previous comment).

[howard-e]

Agreed

Also, I think this probably should count as a font-face test.
