webView: mouseDidMoveOverElement: modifierFlags: callbacks are sent when Exposé is active

[Wade Cosgrove]

If I implement the callback:

- (void)webView:(WebView *)sender mouseDidMoveOverElement:(NSDictionary *)elementInformation modifierFlags:(unsigned int)modifierFlags

I'm messaged with mouse moved events when the parent window of my webView has been moved offscreen by Exposé. As there's no way to determine when exposé is active, this is very troublesome as I show a child window over the webview when getting the mosueDidMoveOverElement message.

For an example of this, use Coda's DOM inspector (www.panic.com/coda) and then activate exposé and mouse around where the webview used to be on screen. You'll see the DOM inspector is showing over a blank area where the webview used to be.
