Shy breaks kerning in Safari 10

Soft Hyphens (&amp;shy; symbol) breaks font's kerning.

Here's an example: <a href="http://codepen.io/stfoo/pen/eBGzwW">http://codepen.io/stfoo/pen/eBGzwW</a>

There is letters pair &quot;AV&quot; that supposed to be kerned. Red ones show text without soft hyphens. First two has kerning switched on, last two — switched off.
Cyan pairs show text with soft hyphens. Kerning for cyan text is always on;

In Safari 10 i see this picture: <a href="http://d.pr/i/EPvt">http://d.pr/i/EPvt</a>. It shows that text with hyphens is equal to text without kerning.
In other browsers (Chrome 54, Firefox 48) it works as intended: <a href="http://d.pr/i/t0Us">http://d.pr/i/t0Us</a>. Soft hyphens are ignored.

Is it a bug?</pre>
