<pre>Apple's hyphenation API seems to behave odd, leading to suboptimal hyphenation in Safari and Chrome on Mac/iOS, see previous discussion at <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=677263">https://bugs.chromium.org/p/chromium/issues/detail?id=677263</a>.
Blink maintainer kojii states:
OS X hyphenation API returns:
"infrastructure" -> "in-frastructure"
"frastructure" -> "fras-tructure"
"tructure" -> "truc-ture"
Attached a specific test case. Results:
Safari on Mac: "in-frastructure"
Firefox on Mac: "infrastruc-ture" (own dictionary)
Safari on Windows: "infrastruc-ture"</pre>
