.test keeps the state when used along with a regex that has the global or the sticky flag. We can prevent that behaviour getting stateless validation using .match

What about using Array.isArray(str.match(pattern)) or str.match(pattern) !== null since the possible return values of .matches are Array or null?
The result is obviously the same, but semantically seems more appropriate to me :)
And maybe they'll be more inclined to accept the PR :)

I honestly find that excessively verbose and probably won't be a blocker for the pr. Let's see what the maintainers think.
