THE PROBLEM:

Closing modal dialog doesn't activate its owner.

HOW TO REPRODUCE:

Compile and run the testcase below.

1. Two frames and one dialog will appear. Make sure the dialog is focused.
2. Alt-tab to the frame "f0".
3. Alt-Tab to the dialog again.
4. Close the dialog.

EXPECTED BEHAVIOR:

The frame "f1" (the owner of the dialog) gets activated.

ACTUAL BEHAVIOR:

The previously active frame "f0" gets activated.


Note that this works fine on Linux.
