title: text-overflow "string" invalid property value Chrome
body: <p>Do anyone know why all default values for text-overflow work in google Chrome except from the "string" value?</p>
  
  <p>if you want to check it you can open mozilla and chrome with this link: <a href="https://css-tricks.com/almanac/properties/t/text-overflow/" rel="nofollow">https://css-tricks.com/almanac/properties/t/text-overflow/</a></p>
  
  <p>then you can go to the first "codepen" box which shows the implementation and inspect the performance when <code>text-overflow: "---"</code> in both browsers.</p>
  
  <p>In mozilla firefox 45.0 works, but in chrome 49.0.2623.87 (64-bit) doesn't.. and the error is invalid property value...</p>
