Be careful when handling the input event. If there's a dialog already open like a subscription dialog when the input event occurs and the action of the input event leads to another dialog like a Resume/Play/Rewind dialog, this new dialog will overtake the old dialog as you'd expect. However, when the new dialog is closed, at some point the old dialog will become visible again unless it's closed properly.
A test that's currently passing is to just close all possible dialogs from within your input event handler.
m.SubscriptionDialog.close = true
m.ResumeDialog.close = true
m.WarningDialog.close = true
