Having the browser zoom level at something other than 100% causes 'icon-image' icons to not display

[subwai]

mapbox-gl-js version: 0.38.0

Steps to Trigger Behavior

Everything tested on macOS Sierra 10.12.5

REPRODUCIBLE: Chrome Version 59.0.3071.115 (Official Build) (64-bit)
REPRODUCIBLE: Firefox 54.0.1 (64-bit)
For some reason this is not an issue in Safari: Version 10.1.1 (12603.2.4)

1. Go to https://www.mapbox.com/mapbox-gl-js/example/add-image-generated/ or https://www.mapbox.com/mapbox-gl-js/example/add-image/
2. Set browser zoom level to 110% (or 90%), by pressing "Cmd +"
3. Reload the page

Expected Behavior

• The icon you try to load in these examples should display

Actual Behavior

• The icon is not displaying at all (however the map base is still there)

The bug only seems to be a problem for the layer property "icon-image".

Hi @subwai, thanks for the detailed report. I was able to reproduce this bug on my macbook pro in Chrome. We will investigate 🕵️‍♀️
