According to this page, NokiaBrowser 7.3 implements new CSS 3 border properties. But I'm unable to active 'border-radius' and 'box-shadow' CSS borders properties.

Here's an excerpt of the code I'm using :

Code:
<head>
  <style type="text/css"> 
    .radius{
        border:2px solid #a1a1a1;
        padding:10px 40px;
        background:#dddddd;
        width:250px;
        height:300px;
        border-radius:150px;
    }

    .shadow{
        width:300px;
        height:100px;
        margin-top:40px;
        background-color:yellow;
        box-shadow: 10px 10px 5px #888888;
    }
  </style>
</head>
<body>
  <div class="radius"></div>
  <div class="shadow"></div>
</body>

With the NokiaWDE 1.2 emulator, only the div.radius element is correctly displayed with rounded corners, the div.shadow has no box shadow displayed.

And on the N97 mini with Browser 7.1.3, both elements don't have these CSS properties active, no rounded corners and no box shadow.

Is something wrong with this code ?
