/locate gives stronghold as a suggestion while in The End and Nether

When you're in The End or Nether dimension and you type /locate then space, you will be given "stronghold" as a suggestion for locate, but there aren't any strongholds in The End or Nether dimensions. Thinking that this is a good suggestion" by typing /locate stronghold will give an error "No valid structure found in this dimension" Then why give the suggestion? There are no structures for "stronghold" in these dimensions.
