Test for bug 76701: map HTTP-EQUIV content-language to -webkit-locale. This particular test tests that a comma-separated list of languages is ignored. This expectation may change, see bug. The HTML5 spec says that content-language should not have multiple languages, and decrees that a content-language containing a comma be ignored; this position has been upheld following significant debate. Firefox accepts a comma-separated list and a CSS :lang selector for any language in the list is matched. It's unclear what IE does.
