zarr.tree() on h5py File in notebook renders with wrong icon for root node and datasets

[alimanfoo]

Problem description

zarr.tree() is designed to work with either zarr Group or h5py File. When passed an h5py File the icons rendered in the jupyter notebook are wrong for the root node (should be black folder icon like groups) and for datasets (should be table icon). E.g.:

Version and installation information

• Value of zarr.__version__: 2.2.0
• Version of Python interpreter: 3.6

Yeah, this must be some underlying representation of jsTree showing up in the representation. It's strange that it only happens with HDF5 files. Maybe something about how we determine what a Dataset is is not working. Perhaps this issue is simpler than it looks.

Is this still an issue with recent releases? Wondering if this is gone after moving to ipytree?
