Type of Change

• Bug fix

Description

When a module emits save_request, if there is any dialog currently, an error generates; this change fixes it. Now, when you emit save_request and there is any dialog, SignalBus will wait until dialog removing and emits save_finished with given callback, so all requests will be handled.

Testing

Works fine and removes error.

Impact

Adds a small delay before duplicate save_finished based on garbage collection speed. This makes closing a little bit slower so it isn't very bad.

Additional Information

Nothing
