Floating grass

A problem that has been occurring for a long time in minecraft, grass floating over lakes. I will show a print that I took from the screen of one of the many lakes that appear with floating grasses, I don't know if there is any other related file but there it is. The version I'm playing is 21w18a and I don't know if the two new versions fixed the error.
If not, I hope you fix that old mistake.
