Symbol interpolation issue when icon-pitch-alignment is "map"

mapbox-gl-js version: v0.54.0-beta.1

browser: any

Steps to Trigger Behavior

1. create a symbol layer with icon-pitch-alignment set to "map"
2. do not rotate or pitch the map

Expected Behavior

Icon should be rendered with NEAREST interpolation

Actual Behavior

Icon is rendered with LINEAR interpolation

Hint: there is a condition in draw_symbol.js:197

pitchWithMap || tr.pitch !== 0

I think it should be just

tr.pitch !== 0

because when icon-pitch-alignment is set to "map", and neither the icon nor the map is rotated, NEAREST should be used. (same as "viewport" alignment)
