[Bug] Message Viewer bugs

After testing out the message viewer a bit, I've encountered some glitches with it. Further testing from the developers may be needed.

1) After using the viewer to display any message, two things happen until a new scene is loaded:
- The Z Button's functionality gets mostly disabled. The input viewer indicates that the game still knows that Z is being pressed, and it can be still be used to scroll left on the Pause Menu. But in normal gameplay, pressing Z to recenter the camera or target does nothing.
- While more message boxes can be spawned with the viewer, it becomes impossible to spawn more messages boxes naturally through reading signs or talking to people, as the A Button prompt stay blank when near those objects instead of displaying "Check" or "Speak". (Other A Button actions like rolling or opening doors are still allowed.)

2) Sometimes, though not always, spawning a message causes the B Button, C Buttons, and minimap to disappear, like what usually happens when a message box appears. But when the spawned message is closed, those UI elements don't return like they should until a new scene is loaded.

3) When spawned, there is at least one vanilla message, the text ID being 0x4000, that cannot be closed after it is finished. Pressing A does nothing to it. The only way to clear it is, again, loading a new scene. This makes me wonder if other text IDs might have the same problem.

This picture was taken after spawning a message with the message viewer. Notice how the A Button is still blank even after standing next to a person.

This picture displays the end of message 0x4000 after spawning it with the message viewer. Pressing A here does not close it.
