Description of the bug

As demonstrated by this failing test:

    public function testIsDepth() : void
    {
        $dom = html5qp('<p><span>foo</span></p>');
        self::assertTrue($dom->is('p'), "Should match element held directly in the collection");
        self::assertFalse($dom->is('span'), "Should not match a descendant of element held in the collection");
    }

->is($selector) will return true if any descendant of an element held in the collection matches the selector. This diverges from jQuery specification, as evidenced by this filddle, and IMO that makes ->is() useless. At the very least, the original functionality of jQuery's .is() should be provided somehow.

QueryPath version

3.2.3

PHP Version and environment (server type, cli provider etc., enclosing libraries and their respective versions)

8.3.4 (cli) on up-to-date Arch Linux

Minimal reproducible PHP+HTML snippet to replicate bug

echo html5qp('<p><span>foo</span></p>')->is('span') ? "Is, but shouldn't be\n" : "Isn't, and that's fine\n";

Thank you for reporting this issue @rulatir. I agree that is() should act like the jQuery equivalent (where possible). It looks like QueryPath's ->is($selector) currently works like ->has($selector), but returns a boolean.
