XPath nth element selector is treated as CSS, and is invalid

[monkeyArms]

A valid XPath selector for nth element, e.g. (//a)[3] is treated as a CSS selector because it does not start with a /, which causes an "invalid selector" exception to be thrown.

Good catch. Maybe could we introduce a new parameter to force the selector to be interpreted as xpath?

It might be nice to have that option. I would think simply changing that line to this would fix the issue as well since CSS selectors cannot start with an open parenthesis:

return empty( $locator ) || !in_array( $locator[0], [ '/', '(' ] )

This works for me. Do you want to open a PR?
