- Get rid of an unnecessary call to uloc_canonicalize in js-locale. - Do not use regex, but rely on ICU for the structrural validity check with Chrome's ICU or ICU 63 or newer. Otherwise, continue to use regex. This became possible thanks to a couple of bug fixes in ICU ToT that were cherry-picked for Chromium's ICU. Not yet done is to change js-locale to use CanonicalizeLocale(). That will make a few more tests pass.
