fixes parts of bug http://code.google.com/p/chromium/issues/detail?id=55764

On IE9 a border is still drawn around all mshtml windows, which does not happen with ChromeFrame.
This needs more investigation.

BUG=55764
TEST=Launch IE9 and navigate to a ChromeFrame enabled page. The ChromeFrame page should not
     have a client edge border.
