Orca disappears from dock when asking to confirm quit

[Alan Jenkins]

1. Open Orca.
2. Press Quit / Close / Alt+F4

=> A "confirm quit" dialog appears. The Orca main window disappears for the duration. (This seems to be intentional, or perhaps considered awkward to fix. The developer who fixed #802447 couldn't have helped noticing it).

=> The Orca icon in the dock disappears, even though the "confirm quit" dialog is still open. The "confirm quit" window has no dock icon associated with it.
