Bug 38587 – @namespaces rules before @import rules are not invalidated

• Component: CSS
• Status: RESOLVED DUPLICATE

proposed fix #1

Per CSS 3 Namespaces spec [1], @namespace rules must follow all @charset and @import rules. This is not enforced at this time by CSSParser, and that's one of the last tests from the Namespaces Test Suite WebKit fails [2].

I have written a patch to fix this bug. Please excuse me in advance if it does not strictly follow WebKit coding style rules or misses an important architectural step: this is my very first patch in WebKit...

Patch is lacking a changelog and testcase, so it's not ready for review, but thanks for the code changes Daniel!

I think the patch is in fact wrong. I ended up implementing the fix the wrong
way because the test in the Test Suite is not really testing the invalidity
of a @namespace but only the invalidity of an @import following a @namespace...

Revamping, stay tuned.
