1614329 - style element's type attribute isn't parsed per the HTML spec rules

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect, P2)

Description

[(no longer active)]

https://html.spec.whatwg.org/multipage/semantics.html#update-a-style-block step 4 specifies that we should only accept "" or "text/css" for the type attribute of style elements. But we currently parse it as a mimetype header.

https://searchfox.org/mozilla-central/source/testing/web-platform/tests/html/semantics/document-metadata/the-style-element/style_type.html is a test for this which fails in Gecko only.
