IIRC the workaround is to use a slice with neighbouring dates which is unintuitive and ugly.

Oh God! Classic pandas...

of course, my search turns up a related pandas issue I filed 5 years ago! https://github.com/pandas-dev/pandas/issues/7827

I agree, this is unfortunate. It's also consistent with how pandas handles indexing from a DatetimeIndex. I'll file an upstream issue.
