dvc list doesn't list contents of dvc-tracked folders

[dldx]

Bug Report

dvc list does not ever seem to list folders or subfolders within a dvc file. If there are dvc files tracking single files, then I do see the file in dvc list, but if I am tracking an entire folder, I do not get anything. DVC would need to download all the .dir files associated with dvc files, which it does not seem to be doing during dvc list

Please provide information about your setup
