Rain passes through moss blocks

As far as I know this is normal - like a leaf, it is a transparent block.

Can confirm in 21w07a. This is the exact same case with powder snow as stated in MC-205442. Rain falls through the moss blocks however, you cannot throw a riptide enchanted trident therefore making this "ghost precipitation" very similar to what MC-205442 states.

Can confirm in 21w10a.

Can confirm in 21w11a.
