Describe the bug
@TestHTTPResource is not properly set if running in native mode with random http port

Expected behavior
Field annotated with @TestHTTPResource should contain the resoved port

Actual behavior
Field annotated with @TestHTTPResource contains port 0, which is the random port

I could work around this in my project by not using a @TestHTTPResource annotated field, but grab the port out of RestAssured.port, which is correctly set to the captured port.

#19002 fixes the issue. We'll try to get it in 2.1.1.Final
