Cannot use `or_insert_with` for `HashMap::<usize, HashMap<usize, i64>>` - is this supposed to be supported?

I have a program like this:

use hashbrown::HashMap;

fn main() {
    let mut value_by_col_by_row = HashMap::<usize, HashMap<usize, i64>>::new();
    value_by_col_by_row.entry_ref(&0).or_insert_with(HashMap::new).insert(0, 1);
}

Unfortunately, cargo build produces the following error:

   Compiling rust v0.1.0 (/my/project/path)

I'm not sure if I'm doing something wrong or if this is not supposed to be a supported use case?

hashbrown = "0.15.2"

Start with the supplied Rust example and inspect hashbrown/src/map.rs around EntryRef::or_insert_with, especially the K: Hash + From<&Q> bound shown in the compiler error. Compare the entry_ref API behavior with the expected nested HashMap use case and its existing tests; done means the supported behavior and any required API or documentation change are clear.
