The href setter needs to reset the query object

[SimonSapin]

The href setter of URL objects is currently:

Let parsedURL be the result of running the basic URL parser on the given value.
If parsedURL is failure, throw a TypeError exception.
Set context object’s url to parsedURL.

This looks like it’s missing additional steps to propagate the change to searchParams, as tested in https://github.com/w3c/web-platform-tests/blob/0a518aaff/url/url-constructor.html#L121-L123. Something like:

Let query be parsedURL’s query, if that is non-null, and the empty string otherwise.
Set context object’s query object to a new URLSearchParams object using query, and then set that query object’s url object to context object.

(Similar to what the URL constructor does.)

Shouldn't rather the associated URLSearchParams instance be updated?

Yeah, we should update the associated instance. So we can use [SameObject].
