Normally it’s fine to just use some semi-related font-lock face for them; mhtml.el uses function-call-face and constant-face for tags and attributes. But because in JSX, HTML tags and attribtues appear in the same buffer with Javascript code, if we use function-call-face and constant-face for tags and attributes, it’s impossible to change their appearance and not affect the functions and constants in Javascript code, because we are using the same face for JS functions and HTML tags, and JS constants and HTML attributes.

Cool. I pushed the change.
