Jonathan Kew 2021cc63fc Bug 1865482 - Make CSS :lang() matching more correctly follow the BCP4647 Extended Filtering algorithm. r=layout-reviewers,emilio ... The matching behavior implemented in bug 1857742 did not quite follow the spec, particularly with regard to language *ranges* (as used in the :lang() pseudo) that are not themselves valid language *tags*. This updates the LangTagCompare function to more correctly follow the BCP4647 "Extended Filtering" algorithm, and adjusts the relevant WPT tests (originally from bug 1857742) to reflect the corrected behavior.
