[Blog/Docs] Zoom bug at 110% – text gets smaller

[html5cat]

Description

Zooming in on docs and blog pages reduces font size at first step instead of increasing it.

Environment

Operating System: MacOS High Sierra, Latest Chrome, 13" macbook pro

Steps to reproduce

1. Open any docs or blog page, i.e. https://www.gatsbyjs.org/blog/2017-11-08-migrate-from-jekyll-to-gatsby/

2. Zoom in one step from 100% to 110%

3. See the fonts decrease in size instead of increasing

Looks like it's just running into our media queries which are adjusting the font size up and down

gatsby/www/src/utils/typography.js

Line 260 in f02cc2b

html: {

This is kinda weird I'll agree — feel free to tweak our media queries to make this edge case a little less "edgy" :-)
