That is because WebBrowser emulates Internet Explorer (I believe, in your case, IE7), and border-radius is only supported on IE9+.

You can check the IE version you're using with WebBrowser.Version

Gets the version of Internet Explorer installed.

I found a blog post tutorial on how to change the default IE version, but here's the sum up:

If you have control over the HTML you're displaying:
- If you want the latest possible IE version:
  
  Add the following tag to your <head>:
```
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
```
- If you want a specific IE version
  
  Check this answer with the list of <meta> tags.
If you don't have control over the HTML:

Well, it's complicated. That requires that you edit the FEATURE_BROWSER_EMULATION key in the Windows Registry. You can check this answer that teaches exactly how to do that.
