        <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:
    &quot;infrastructure&quot; -&gt; &quot;in-frastructure&quot;
    &quot;frastructure&quot; -&gt; &quot;fras-tructure&quot;
    &quot;tructure&quot; -&gt; &quot;truc-ture&quot;

Attached a specific test case. Results:

    Safari on Mac: &quot;in-frastructure&quot;
    Firefox on Mac: &quot;infrastruc-ture&quot; (own dictionary)
    Safari on Windows: &quot;infrastruc-ture&quot;</pre>
