Which @angular/* package(s) are the source of the bug?

common/http

Is this a regression?

Yes

Description

After update to angular14, a function in our project which use HttpClient.jsonp() not work any more.

We finded out that HttpClient.jsonp in v14 will throw an error if the headers in reqeust is not empty, and that what make matters worse is that in the project we import HttpClientModule which provides a HttpXsrfInterceptor before HttpClientJsonpModule, so before JsonpInterceptor can handle the jsonp request, the request was already intercepted by HttpXsrfInterceptor and a xsrf header was already added to the request which caused the 'JSONP requests do not support headers' Error

I don't think is resonable that we must import HttpClientJsonpModule before HttpClientModule to use jsonp. May be HttpXsrfInterceptor should escape if request.method is jsonp, i'd like to help if angular team agree with this.
