The intention of the split commits was for this test to overwrite the suggest_value_path_without_mapper, showing the change in behavior. Only the call to map and output should change in this commit.

So @epage, i should do that same as i did for suggest_value_path_with_mapper (in the first commit showing the behaviour without mapper and then showing the behaviour with mapper right ?)

If you ran clippy on this, it would complain about the use of map_or. CI isn't catching it because we aren't running it on unstable features from non-default packages.
