Bug 80515 – HTML meta http-equiv "Content-Style-Type" not supported

• Status: RESOLVED
• Resolution: WONTFIX
• Component: CSS

[Pravin D]

Overview: 
meta http-equiv "Content-Style-Type" is used to set the default style sheet language for a document. Any HTML tag having a style attribute must use the default style sheet language set by "Content-Style-Type" to parse the style content. If default style sheet language is not set then CSS will be set as the default style sheet language. 



Steps to Reproduce: 
1) Fetch the test URL
2) Observe how ~(41a). Style set by style attribute in a language tagged as "text/nonsense".~  is rendered.

Expected Results:
The text ~(41a). Style set by style attribute in a language tagged as "text/nonsense".~  must not have any styling, i.e text must be black with white background color.

Actual Results:
The text ~(41a). Style set by style attribute in a language tagged as "text/nonsense".~  has styling with the text color as "red" on yellow background.

Builds and Platforms: Reproducible on all platforms and build

Additional Information:
1) The test URL has a good explanation of the test case .
2) For information on meta http-equiv "Content-Style-Type" refer to:

Does this work in other browsers? Is there any existing content depending on this?

I have verified this on firefox both on linux ( ubuntu 11.10 64-bit ) as well as on windows 7. It works as expected. Whereas webkit based browsers show this particular line in red color.

We do not aim to support pre-HTML5 features.

Anything that's in earlier standards but not in HTML5 is presumed to be unnecessary for web compatibility.
