Generated related pages too generic

The related pages links that are generated by selecting the checkboxes
under "Topic Clusters" of the "See Also" section when editing are too
general/broad. For example, on the disabled attribute [1] page I am seeing,
* BGCOLOR
* HTMLAudioElement
* Pointer Events Primer
* List
* height
* !doctype
* dl
* head

etc. A bunch of almost completely unrelated things. Is there a reason that
these are generated?

I think it would be best to remove this generation of links in favor of
simply having editors manually cross-link related things. That way we get
higher-quality links that are known to be related in some way to the
content at hand.
