While using the new touch controls, both the Left and Right Action Buttons could be used in order to tune and play a noteblock, while it should only be possible with the right click button as it is an interaction. 

Steps to reproduce;

1. Place down a noteblock.
2. Enable the new touch controls for Android and iOS, on crosshair mode.
3. Use the Right Click Action button to Tune/Play the noteblock.
4. Then use the Left Click Action button to Play the noteblock.

Expected results:

Only the right-click button can be used to play Noteblock, nothing happens when using left click button. 

Observed results:

Both buttons are able to play/tune the noteblock. 

In the below video, Noteblock is compared to the Bell which can only be Played/Ringed using the right click and not left.
