Windows 8 and 2008R2 RD Web Access not showing icons

I did some testing with Windows 8 Consumer Preview and our 2008 R2 Web
Access site and found that the icons were not displayed correctly:

However, if you use IE10 Compatibility view, the icons are displayed correctly:

As i think this is a beta-kind of issue, so i posted this in the tech forum and it seems they picked up the issue, but sadly this was not fixed in Windows 8 Release Preview. I hope this will be picked up in the RTM version though..

Update: I’m afraid this issue occurs also in the Windows 8 RTM version, even with all the available updates installed (7th January 2013).
