[css-pseudo-4] [css-highlight-api-1] Integrating custom highlights into css-pseudo-4 #6755
Description
Should the custom ::highlight pseudos be mentioned among the other highlight pseudos defined at https://drafts.csswg.org/css-pseudo-4/#highlight-selectors?
Custom highlights are different from the other pseudos in that they have their own standalone spec, but it seems like there should be at least a note about them in [css-pseudo-4] where the other highlight pseudos are covered.
I attempted to integrate them here: #6754. Not sure if that is the right approach.
