Decoding failure when roundtripping datetime via Icechunk #686
Description
#677 introduced support for datetime dtypes, but one xfail test still fails. In #677 I kept that specific xfail in, but I don't know why I had to.
It only happens when roundtripping via Icechunk, which fails with an error inside xarray's zarr decoders...
Run https://github.com/zarr-developers/VirtualiZarr/actions/runs/16343336520/job/46170930960#step:5:837 has the error message
