script: Fix handling of invalid fetch responses for link stylesheets by TimvdLippe · Pull Request #42037 · servo/servo

TimvdLippe · 2026-01-20T19:19:29Z

Regardless of the Ok status, we should always create a
stylesheet. However, the determining of the load/error event
is based on whether it has parsed actual content or not.

It also realigns some of the spec text to now only do it for link
elements, since for styles we shouldn't be checking the result of
the content type.

Part of #22715

🤖 Opened new upstream WPT pull request (web-platform-tests/wpt#57295) with upstreamable changes.

These should cause it to fail, regardless of the Ok status. To do so, we remove the `bool` and use the `Option` to convey success/failure. It also realigns some of the spec text to now only do it for link elements, since for styles we shouldn't be checking the result of the content type.
