Incorrect Azalea Tree spawn

I saw it in 23w43a but should work on 1.20.2 too.

 

I was in spawn and then I saw 2 azalea trees which spawn near to a beach but they were in the water on sand blocks.

 

Not a dupe of MC-218592 beacuse I have the azalea 1 block deap in the ground.

 

World type: "Deafult" (probably you could see from the screenshots but I included it anyway)

No bounse chest.

Generate Structures on.
