Bug in URL and/or URLSearchParams classes - Cannot overwrite or add URL parameters when parameters are already present in the URL

[EmilJunker]

Description

When a URL object already contains parameters, adding or overwriting parameters via the url.searchParams or url.search attributes does not work correctly.

Steps to reproduce

const url = new URL('https://example.com/api/data?foo=bar&baz=qux');

url.searchParams.set('foo', 'newFoo');
url.searchParams.set('test', '12345');

console.log(url.toString());
// expected output: https://example.com/api/data/?foo=newFoo&baz=qux&test=12345
// actual output:   https://example.com/api/data?foo=bar&baz=qux&foo=newFoo&baz=qux&test=12345

url.search = 'foo=overwritten&hello=world';

console.log(url.toString());
// expected output: https://example.com/api/data/?foo=overwritten&hello=world
// actual output:   https://example.com/api/data?foo=bar&baz=qux&foo=newFoo&baz=qux&test=12345
