The features minecraft:bamboo_no_podzol and minecraft:bamboo_some_podzol are also affected (when placed on a non-dirty block, like stone). It looks like the issue here is inconsistent ways that features abort placement (which doesn't matter in worldgen, but does matter in the user-facing placefeature comand).

Hello, while this is a very good bug report–the issue is with these features and not the placefeature command. I am marking this invalid, and splitting out each of your listed bugs into their own bug. Thanks!
