📚 Description

Because we are using the scanned links to create a new URL we need to ensure they are decoded first:

nitro/src/prerender.ts

Lines 396 to 404 in df7091d

	const _link = parseURL(link);
	if (_link.protocol) {
	continue;
	}
	if (!_link.pathname.startsWith("/")) {
	const fromURL = new URL(from, "http://localhost");
	_link.pathname = new URL(_link.pathname, fromURL).pathname;
	}
	links.push(_link.pathname + _link.search);
