Research direction

Start by comparing the repository's locale fallback behavior with the referenced CLDR upstream implementation in LocaleIDParser.java, lines 121-148. Reproduce a fallback case involving a locale script and verify that it falls back to :root rather than a non-default script; done means the incorrect fallback is corrected and the behavior is covered by the project's tests.

Written by the indexing model from the issue text.

Description

When falling back through locales, we don't want to fallback to a non-default script, and should instead fall back to :root

Refer to this code in the CLDR upstream:

https://github.com/unicode-org/cldr/blob/2ef01fbbb2a3de93f241e51dd8e37a4b37ae54be/tools/cldr-code/src/main/java/org/unicode/cldr/util/LocaleIDParser.java#L121-L148
