+  Call Intl.getCanonicalLocales function with grandfathered language tags.
+info: |
+  8.2.1 Intl.getCanonicalLocales (locales)
+    1. Let ll be ? CanonicalizeLocaleList(locales).
+    2. Return CreateArrayFromList(ll).
+
+  9.2.1 CanonicalizeLocaleList (locales)
+    ...
+    7. Repeat, while k < len
+      ...
+      c. If kPresent is true, then
+        ...
+        v. Let canonicalizedTag be CanonicalizeLanguageTag(tag).
+      ...
+
+  6.2.3 CanonicalizeLanguageTag ( locale )
+    The CanonicalizeLanguageTag abstract operation returns the canonical and case-regularized
+    form of the locale argument (which must be a String value that is a structurally valid
+    BCP 47 language tag as verified by the IsStructurallyValidLanguageTag abstract operation).
+    A conforming implementation shall take the steps specified in RFC 5646 section 4.5, or
+    successor, to bring the language tag into canonical form, and to regularize the case of
+    the subtags. Furthermore, a conforming implementation shall not take the steps to bring
+    a language tag into "extlang form", nor shall it reorder variant subtags.
+
+    The specifications for extensions to BCP 47 language tags, such as RFC 6067, may include
+    canonicalization rules for the extension subtag sequences they define that go beyond the
+    canonicalization rules of RFC 5646 section 4.5. Implementations are allowed, but not
+    required, to apply these additional rules.
