Sometimes when opening Excel you may seem to land in a clipboard manager. Similarly if you open MS Word after a crash, you may seem to land in a file recovery pane. However, trying to interact with these panes does not work, and typing characters types directly into the document. In short, these panes incorrectly fire focus events whtough actually taking the system focus. We should ignore focus events on SDM controls if their window does not match hwndFocus on the GUI thread.
