When selected preference>advance>style sheet to zoom. Cheak box and radio looks odd.

In safari 8. After updated OS X to Yosemite. When set preference>advance>style sheet to xxx.css.

In xxx.css contain :

body {

zoom: 110%;

}

Safari will show checkbox and radio box in all website distortion. As shown below.

Cheak box looks odd and invisible radio box.

Please, tell me. What caused it Or is it a BUG.

Thank You.
