I had Japanse in my list of "Preferred Languages" in the Language & Region system settings on Big Sur, and this causes a subset of layout tests to fail, including: fast/ruby/ruby-justification.html fast/text/backslash-to-yen-sign-euc.html and tests with "ideograph" in the name. We need to fix WTR to make tests pass independently of system language settings.

Fixing DRT would be super difficult (bordering on "impossible") here. Fixing WKTR is probably not very difficult. We already have infrastructure for mocking the system font. We probably should just always enable that infrastructure.
