Clay and moss are blocks that are able to support small dripleaf plants outside of water due to its implied moisture. By that logic, mud should be included in this list.

@unknown you're misunderstanding the issue here, they mean that mud is a wet block that contains water, just like clay, which small dripleafs can be placed on without water. And thus small dripleafs should be placeable on mud too.
IMO this makes sense as mud needs to get "dried out" to get clay using a stalagtite. Might still be a feature request though.
I think there's a bit of misconception here. As far as I am aware, the #minecraft:small_dripleaf_placeable block tag is only included on blocks that can support small dripleaves without the presence of water. Similar blocks such as podzol, coarse dirt, rooted dirt, etc... also don't have this block tag despite small dripleaves being able to be supported by them but only with the presence of water. This leads me to believe that this issue is working as intended, however, that isn't my decision to make, but nonetheless, I can confirm this behavior.
