Placing water with a dispenser facing a water source drops the bucket

The bug

In previous versions, if a dispenser is facing a water source and has a full water bucket, placing it would just empty the bucket and keep it in the dispenser (after making a water placing sound).

In this version, the dispenser makes the placing sound, but then it drops the bucket, which is still full.

To reproduce

1. Place a dispenser facing a water source block
2. Put a water bucket inside of the dispenser
3. Power the dispenser
   → The water bucket is dropped instead of emptied
