Azalea Tree generates in Aquifers Water of Caves

Hi Mojang and Mega Spud! Today yesterday i recently was testing the game to find a bug and i found a bug that is related to Azalea Tree when you saw some vines on the grass blocks it's means that lush cave is near you and then i go to straight down and found a aquifers which was having a lot of vines then i saw that the Azalea Tree was generating in the Aquifers water and we know that all the tress do not generate in water, aquifers, rivers and ocean they generate on land and the Azalea Tree is generating in undergrounds water of caves which is known as Aquifers so please fix this issue and here is the screenshot i take of the Azalea Tree generating in underground water which is called Aquifers so kindly fix this issue.
Thankyou!
