I believe the issue here has to do with the rendering mode inside of the control. Proper HTML5 content with the appropriate doc type headers will render without a border. But content that's not using IE Edge mode (ie. IE7 rendering) will render with the 3d frame.
IOW, this is driven by the engine.
Make sure the pages you're displaying are using HTML5 compliant header:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" /> This works for me to get borderless windows.
For other browsers the DocType is no longer needed because the pre-presumption is HTML5 mode, but for IE it needs the hint otherwise it renders in Quirks mode which is what apparently brings up the crazy borders.
