Subject: [PATCH 1/2] workspace: Focus only ancestors that are focusable
|
|
|
88c283 |
|
|
|
88c283 |
When destroying a window that has a parent, we initially try to focus one of
|
|
|
88c283 |
its ancestors. However if no ancestor can be focused, then we should instead
|
|
|
88c283 |
focus the default focus window instead of trying to request focus for a window
|
|
|
88c283 |
that can't get focus anyways.
|
|
|
88c283 |
|
|
|
