0.23.0 breaks some fill layers that use fill-pattern

[dpieri]

mapbox-gl-js version: 0.23.0

When using 0.22.1 and earlier, a fill layer with fill-outline-color and fill-color and fill-pattern specified will render the pattern, but not the color or outline (as is expected based on my reading of the style spec).

As of 0.23.0 the same layer will now be rendered with no pattern and no color.

To further complicate things, the issue described above does not surface if you use a hex color instead of hsla(). If you use a hex then the pattern renders as expected.

Examples

0.22.1 + hsla(), pattern does render: http://jsbin.com/xujowiqeno/1/edit?html,output

0.23.0 + hsla(), pattern does not render: http://jsbin.com/zifoxutavo/1/edit?html,output

0.23.0 + hex(), pattern does render: http://jsbin.com/mozefaxura/1/edit?html,output

Expected Behavior

Pattern renders.

Actual Behavior

Pattern does not render.
