RFR: JDK-8241544 update stylesheet for *-page CSS class rename and hyphenated naming

Wed Mar 25 15:53:35 UTC 2020

Hi Jon,

It's nice to see this change addresses a visual regression caused by the recent
changes. Thanks for providing detailed comments for "additional class names"
in the new test.

Nit. Could you change the name of `addExtraCSSClassNames` to `addExtraCSSClassNamesTo`
or, better still, rename it and make it create a new immutable set rather than
mutate the passed one.

This change looks good to me.

The test determines the set of known CSS class names, based on the CSS class names defined in the stylesheet, and a set of known additional class names, and then reads the output generated from a small sample API, and verifies that the values of all the "class" attributes are in set of known CSS class names.
