What is the purpose of WriteHeaderNow?

[nhooyr]

Why does gin deviate from net/http in that WriteHeader doesn't actually write the header?

You have to call WriteHeaderNow()

gin/response_writer.go

Line 69 in 094f9a9

func (w *responseWriter) WriteHeaderNow() {

This is causing coder/websocket#166

I'll add a fix in my library to call it but I would prefer if gin deprecated this behaviour or added some docs explaining why its necessary.

I ended up patching my library to call it on the response writer if implemented :(
