Inject.rawHead injects at the end of <body> tag

This is a weird issue: my code gets injected in the wrong place, at the end of `<body>` instead of the end of `<head>`.

This also happens with just having code in a plain HTML file and using the `static-html` package so it might not be directly related to inject-initial. But I thought maybe you'd have an idea of what's going on?
