I'm loading content with video using Drupal 7 AJAX Framework.
In the FF and Chrome all working as expected.
But in the IE all added video.js elements come unstyled.
It appears, that something wrong with injected style definition in the head tag:
the first item in the head is empty DIV
and then @import url( http://localhost/chilibrand/sites/all/libraries/video-js/video-js.min.cs... );
