3D Prints switch off when given a block update

[MineRobber9000]

Title. If you attempt to turn a 3D print on while there is an adjacent 3D print already in the "on" state, both prints turn off. Similarly, placing a 3D print next to a 3D print in the "on" state causes the already-placed 3D print to toggle.

Also, not sure if this is a related bug or not, but a 3D print in the "on" state next to a computer that turns on/off will also turn off.

Actually, apparently, doing anything that causes a block update will cause the 3D print to turn off (place block, break block, cause block to update). Not sure if this is related to any button-mode specific code?
