Can someone explain why Sencha Toolbar CSS is not working for Chrome?
===

I have a top docked toolbar, and I used firebug to inspect the element to find the css class, which was: 

      .x-toolbar-dark.x-docked-top 
      {
          border-bottom-color: #000000;
      }

I changed this to:

      .x-toolbar-dark.x-docked-top 
      {
         border-bottom-color: #000000;
         background-color: transparent !important;
      }

Now I see the toolbar as transparent in Firefox, but in chrome it still has the default background color (blue).  Why does this happen?  Maybe I don't need to use this technique here, but there are definitely instances where I need to find a very specific css class using firebug.  Any help or information?

Note: I tried using the Cls attribute of the toolbar with the same result.
