Description

Writing a normal 1-byte bool into a dataset of type `H5T_NATIVE_B8` shows up empty in HDF Compass, even though the data is there and can be read back, or viewed with h5dump. See the top window on the attached screenshot.
Cheers!

**15 min later:** I just realized that the "B" in `H5T_NATIVE_B8` stands for bitfield and not bool. In fact `H5T_NATIVE_UINT8` does show up and fixes my immediate problem. In any case, the file using `H5T_NATIVE_B8` seems well formed and the dataset not showing up could be a bug.
