        <pre>It is possible that this issue is related to this: <a class="bz_bug_link

   title="NEW - Zero-width spaces are rendered incorrectly using -apple-system font"
   href="show_bug.cgi?id=147845">https://bugs.webkit.org/show_bug.cgi?id=147845</a>

Here is a reduction. Only tested this on Yosemite/Safari 9. Click the button to toggle -apple-system being applied in the body font stack.

Basically, if you have a wrapping element with font-size: 0 and line-height: 0 set and any number of elements set to be inline-block there should be no white-space rendered between those blocks. However, when using -apple-system in the font-family property, white-space is rendered regardless. 

This can be problematic for layouts that rely on this technique to produce columns (sane problem with inline-flex too).

Are there any known workarounds CSS wise? I realise that whitespace could be removed in the DOM but in case users don't have the ability to remove the whitespace from the DOM are there any alternatives?</pre>
