fill-opacity not interpolated correctly outside of a tile's zoom range

[ansis]

mapbox-gl-js version: 1.4.0

browser: all

Steps to Trigger Behavior

1. Create a style with an opacity expression that uses linear interpolation with both zoom and a data property:

"fill-opacity": [
            "interpolate",
            ["linear"],
            ["zoom"],
            0.5,
            0,
            1,
            ["match", ["get", "fakeprop"], "nope", 1, 1]
        ]

2. start at zoom 0
3. zoom to zoom 2

Link to Demonstration

I'm opening a PR with a patch and regression test soon. This issue is just to document the problem.

Expected Behavior

Opacity is applied as intended.

Actual Behavior

Opacity is interpolated to a value greater than 1 resulting in the incorrect color for the split second before new tiles are loaded.
