Incorrect output starting with v1.4.2

[jmooring]

Note that the input string contains \r\n. There are no problems when \n is used instead of \r\n.

func main() {
	md := goldmark.New(
		goldmark.WithRendererOptions(
			html.WithUnsafe(),
		),
	)

	input := "<a \r\nhref='link'>link</a>"

	var buf bytes.Buffer
	if err := md.Convert([]byte(input), &buf); err != nil {
		panic(err)
	}

	fmt.Println(buf.String())

}

Output with v1.4.1 (PASS):

<p><a 
href='link'>link</a></p>

Output with v1.4.2 and v1.4.3 (FAIL):

<p>&lt;a
href='link'&gt;link</a></p>

Uff, I just tried to debug for an hour why there were some weird renderings. Here's another interesting example.

The HTML code to feed Goldmark:

<video autoplay muted loop>
    <source src="https://example.com/example.mp3" type="video/mp4">
    Your browser does not support the video tag.
</video>

As an input with \r\n as end line:

input := "<video autoplay muted loop>\r\n<source src=\"https://example.com/example.mp4\" type=\"video/mp4\">\r\nYour browser does not support the video tag.\r\n</video>"

The output will be:

<p><video autoplay muted loop></p>
<source src="https://example.com/example.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>

Which is... broken.
