The Bugbug bot thinks this bug should belong to the 'Core::JavaScript: Internationalization API' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I think this will be fixed when updating to ICU 68, therefore I'm setting bug 1686052 as a blocker for now.

Attachment: Bug 1697729: Re-add alias and parent links in ICU filters. r=tcampbell!

The -/* filter also removes the alias (%%ALIAS) and parent locale (%%Parent)
links, so we have to manually add them back when we're using -/*.

The ICU docs warn about this issue, but unfortunately that warning wasn't
present when we originally created our filter file, so this bug went unnoticed
for a long time.
