Pointed dripstone does not grow with waterlogged block 2 blocks above it but does fill cauldron

When dripstone is hung from a block with a waterlogged block above it, it will fill a cauldron but it won't grow.

 

Steps to reproduce:

• Hang a pointed dripstone from a dripstone block
• Place a water source on top of the dripstone block
• Place any waterloggable block inside of the water source
• Set randomtickspeed to 10000 and wait (also tested with lower tickspeed)

 

Expected behaviour:

• When having a cauldron placed under the pointed dripstone it will fill
• The pointed dripstone will grow

 

Actual behaviour:

• When having a cauldron placed under it it fills up
• The pointed dripstone does not grow

 

Attachments are a comparison of dripstone with a water source and with a waterlogged block above it, this is with the tickspeed at 10000 and after waiting ~5 minutes wich is more than enough for the dripstone to grow.

Also wanted to make clear this is not a duplicate of MC-227104, I am placing the waterlogged block 2 blocks above the dripstone not directly above it.
