LocaleMatcher doesn't work on propietary tags

[ImUrX]

Which package?

intl-localematcher

Describe the bug

I was previously using an old version (0.2.32) which properly matched to proprietary tags if they were used but now with the latest version (0.5.4) it doesn't

To Reproduce

const { match } = require('@formatjs/intl-localematcher')
console.log(match(["en-x-owo"], ["en","en-x-owo"], "en")) // outputs "en" on newer version and "en-x-owo" on the old version

Expected behavior

For it to return the proprietary tag if it's the one being matched
