When putting #3861 to practice, I realized that it's a bit hard to use, because the headless test server might open on a different port every time. It's better to copy the port from the server when it isn't specified. So for example when it happens to open on
127.0.0.1:23456and WASM_BINDGEN_TEST_ADDRESS is set tohttp://localhost.mydomain.orgwe should connect tohttp://localhost.mydomain.org:23456in the test runner (not the default port 80).
