You cannot feed brown mooshrooms flowering azaleas or flowering azalea leaves

The Bug

Normally with flowers that make suspicious stew you can feed them to brown mooshrooms to get the suspicious stew from them. Since flowering azaleas and flowering azaleas can now make suspicious stew you cannot feed them to brown mooshroms to get suspicious stew.

Reproduce

• Get a Brown Mooshroom
• Feed it a small flower like a wither rose
  Notice it eats it
• Get another Brown Mooshroom
• Feed it a Flowering Azalea or Flowering Azalea Leaves
  Notice it doesn't eat them
