The Platform Preview is an early look at the Internet Explorer 9 platform so some features are incomplete, some may change, and some may be added. Microsoft asks that you refrain from providing feedback on features where noted that they are either partially implemented or not available. Microsoft is aware of their condition and will provide updates in future releases. Similarly, for known issues, Microsoft is also aware of their existence and are actively working on them.
