Details

(Whiteboard: [necko-triaged])

The following tests are failing in Firefox but passing in Chrome and Safd

/mimesniff/mime-types/charset-parameter.window.html [7 subtests]
▶ /mimesniff/mime-types/parsing.any.html [317 subtests]
▶ /mimesniff/mime-types/parsing.any.worker.html [317 subtests]

See https://jgraham.github.io/wptdash/?bugComponent=testing%3A%3Aweb-platform-tests

I'm not super sure if this bug actually belongs in DOM:Networking or some other component. Andrea, maybe you know?

Thomas Wisniewski should know more about mimesniff implementation in gecko.

Anne, have we sorted out that the fact that the WPTs expect blob contentTypes to go through the MIMESniff parser, but the spec does not? I think that was one of the blockers here.

Blob/File is indeed not specified properly, tracked by https://github.com/w3c/FileAPI/issues/123 among other issues, but there was rough agreement on going in the direction these tests assume. (Added a link to that prior discussion to this issue.)

These tests are also for Request/Response, which have an updated specification that should match the behavior of these tests.

Flags: needinfo?(annevk)

So we're waiting on the spec work to finish?
