FORM with an action URL containing a query param is not submitted.

Hey all, I am upgrading from Turbo version 7 to version 8 and have observed an issue with a FORM submit.

When the FORM has an action that contains a url param, the param is not submitted with the request

<form  action="/foo/bars?id=12" method="get">

<input type="text" name="query[x]" id="1">
<input type="text" name="query[y]" id="2">
</form>

When the form is submitted, the request is missing the id param from the form action: GET http://localhost:3000/foo/bars?query[x]=1&query[y]=2

Previously, using Turbo version 7, the request would include the url param in the form action. eg GET http://localhost:3000/foo/bars?id=12&query[x]=1&query[y]=2

For additional context which may be relevant, the form is submitted using a Stimulus controller this.formTarget.requestSubmit()

If this is expected behaviour I'll fix my code to deal with it. I couldn't find anything in the W3C standards to indicate a url param is not invalid in the context of a form action.

Apologies, the W3C spec would indicate my scenario is invalid. I'll change my code to be compliant.

If the method is "get" and the action is an HTTP URI, the user agent takes the value of action, appends a `?' to it, then appends the form data set, encoded using the "application/x-www-form-urlencoded" content type. The user agent then traverses the link to this URI. In this scenario, form data are restricted to ASCII codes.
