"Links to the multipage version of the specification are unfortunately likely to break over time." -- https://html.spec.whatwg.org/multipage/asefij.html This commit removes all references to the specific pages when viewing WHATWG using multipage mode. I went through all these links and they redirect fine. Regex used to generate this commit: `s_whatwg.org/multipage/.*#_whatwg.org/multipage/#_g`
