Description
**mapbox-gl-js version**: v0.51.0
**browser**: Chrome 70.0.3538.77 (64-Bit) on Linux
### Steps to Trigger Behavior
Use the mousewheel for zooming in and out.
### Link to Demonstration
https://www.mapbox.com/mapbox-gl-js/example/simple-map/ with `hash: true`
### Expected Behavior
Zooming in and out happens faster, at least 0.25 zoom level per mousewheel "click".
### Actual Behavior
Only 0.08 - 0.09 zoom level per mousewheel "click".

Research direction
Reproduce the behavior with the linked simple-map example using hash: true in Chrome on Linux, then trace the mousewheel zoom handling in the mapbox-gl-js source. Done means mousewheel clicks produce the expected faster zoom increments without breaking zoom behavior in other browsers or platforms.
