Pick block doesn't work on filled cauldron

When I press the pick block button while facing a filled cauldron (water or lava) I expected to get a normal cauldron but what actually happened was I got nothing. this was probably caused by moving 'minecraft:cauldron[level=3]' to 'minecraft:water_cauldron[level=3]' and adding 'minecraft:lava_cauldron' but forgetting to add pick block data to 'minecraft:water_caldron' and 'minecraft:lava_cauldron'

 

How to reproduce

1. Place a cauldron
2. Fill it with water or lava
3. Press the pick block button (default Middle Click or Button 3
   -Notice how nothing happens
