unit tests failing on windows/deno for %@event

[lowlighter]

Scope

http, repo

Environment

deno, windows

What is happening?

Followup of #56, #53

All the tests on deno + windows works except for the http/event directive for some reason (the regular http directive work as expected)

It can be narrowed down to:

mizu/@mizu/http/mod.ts

Lines 167 to 170 in 2099e6f

	const $response = fetch(url, { redirect, method, headers: state.$headers as Headers, body: state.$body as BodyInit })
	if ($event) {
	await renderer.render(element, { ...options, state: { ...state, $event, $response: await $response } })
	}

The response "vanishes" in the void. There is no "apparent error", at least trying to catch the error with try/catch or .catch() has no effect. not sure if it gets caught by jsdom global error handler ?

While I was not able to confirm the promise to resolve, I do think it eventually resolves since the test still completes.
All the errors of this directive are probably the same one, the http server doesn't seem to receive the request (and does not errors too, checked with .on(error)) so there is definitely something strange

It could be an upstream an error
