Legend displays intermittent lake or pond with gray fill instead of light blue

Maybe because the intermittent fill uses a semi-transparent color value?

This might be due to some tweak I made after opening #632 or it might be related to #637. The screenshots in #632 (comment) show that it worked at the time I opened the PR.

The cause seems to be the waterIntermittentFill constant added in #637:

The feature querying result comes back with an evaluated color object where each component is premultiplied by the opacity. The legend code produces rgba(58.199999999999996, 64.8, 72, 0.3) instead of rgba(194, 216, 240, 0.3).
