Steps to Reproduce:

Run the attached project. It is a custom view covering the whole NSWindow, and autoresizing to match the window's size. The view has a 

          [[NSTrackingArea alloc] initWithRect:frame
                                       options:NSTrackingMouseMoved |
                                               NSTrackingMouseEnteredAndExited |
                                               NSTrackingActiveInActiveApp |
                                               NSTrackingInVisibleRect
                                     owner:self
                                  userInfo:nil];

and NSLog()s on mouseMoved:

Now put the mouse cursor on the inside of the window in the lower left corner, so that a resize cursor appears. Size the window bigger by dragging your mouse the the left and down, slowly. Stop after a few pixels. Move the cursor to the middle of the window.

Expected Results:

mouseMoved: messages continue to be sent to the view.

Actual Results:

mouseMoved messages stop being sent after resizing the window from its lower left corner.

Regression:

This broke when all-window-corner resizing was introduced in 10.7 as far as I can tell.

Notes:

This breaks mouseMoved events in chrome.
