Some items that would normally not trigger sculk sensors when right-clicked in the main hand can generate vibrations when right-clicked in the offhand instead. These items are:
Shields
Bows, crossbows, tridents
Spyglass
Food
Note that this isn't talking about the item completing it's animation, just about right-clicking it.
Expected behavior
The listed items would not generate vibrations when right-clicked in the off-hand.
How to reproduce
Get a one of the listed items and place a sculk sensor.
Right-click the item in the main hand, notice how it doesn't trigger the sensor.
Swap your item to your offhand.
Right-click the item again in the offhand and notice how it does trigger the sensor now.
