Our HTML Parser has raw text handling for <noembed> content only if plugins are runnable. However, the HTML specification doesn't ask such behavior [1], and it doesn't match to our HTML serializer. We should always handle it as raw text. Blink already made this change in https://chromium-review.googlesource.com/c/1477556.
