Pointed dripstones under lava takes too much time to fill up the cauldron below the pointed dripstones with lava

Overall Description:

Dripstones take too much time to fill up the cauldron below with lava when it is placed under a lava source. I am aware that this was once reported in Jan 2021 and fixed in a 1.16 beta, but the bug still appears as of Mar 2022 (1.18.12).

Steps to Reproduce:

Place a lava source on top of a floating block. Then place a pointed dripstone under the block.

Below the pointed dripstone, place a cauldron and keep the chunks with this set up simulated.

Expected Results:

The cauldron should have lava generated.

Actual Results:

I have kept the chunk simulated for tens of Minecraft days, but the cauldron has nothing for me.
