Please review a change to fix a couple of accessibility errors in JDK API
documentation as detected by our accessibility testing.
- Contrast between link and normal text colors was below 3 and therefore would
have required other styling (such as underlining). This was fixed by slightly
darkening text color (our text color isn't black but dark-gray).
Resulting colors:
https://webaim.org/resources/linkcontrastchecker/?fcolor=181818&bcolor=FFFFFF&lcolor=437291
- Links in the headings of inherited member summaries used the wrong color and
contrast to background color was below 4.5. This is fixed by removing a bogus
`.expanded` selector that shouldn't have been there in the first place.
Resulting colors:
https://webaim.org/resources/linkcontrastchecker/?fcolor=181818&bcolor=DEE3E9&lcolor=47688A
- Remove the `role="tablist"` and `aria-orientation="horizontal"` attributes
from table captions if they do not contain tabs. This is the only code change,
and the only change that comes with a test change (I guess the CSS changes are
`noreg-hard` as we don't have a way to do automatic accessibility testing).
All changes are invisible or so subtle that they are practically impossible to
spot in normal browsing, so I spare myself the task of uploading demo docs.
