When a modal that's not on top of the modalActorFocusStack gets popped,
|
|
|
22c471 |
we shift the focus stack as described in popModal() to ensure the chain
|
|
|
22c471 |
remains correct. That however destroys the association of a modal actor
|
|
|
22c471 |
and its prevFocus actor on the focus stack, because the prevFocus actors
|
|
|
22c471 |
are now moved to different entries of the stack.
|
|
|
22c471 |
|
|
|
22c471 |
Now when a prevFocus actor gets destroyed, we don't handle that case
|
|
|
22c471 |
correctly and search for the modal actor that was associated with the
|
|
|
22c471 |
prevFocus actor before the stack was shifted, which means we end up
|
|
|
22c471 |
unsetting the wrong prevFocus actor.
|
|
|
22c471 |
|
|
|
22c471 |
So fix that and search the stack for the prevFocus actor which is being
|
|
|
22c471 |
destroyed instead to unset the correct entry.
