(1) Make the "experimental keyword mode bubble outline" color match the keyword
    color.  It already did in light mode; not matching in dark mode looks like
    an oversight.
(2) Make these two colors both match the dropdown URL color.  They were already
    very close, and I believe we intended them to match, but then tweaked the
    URL color in the dropdown to guarantee sufficient contrast in the hovered
    case.
