I can confirm, but it seems that Blender itself does not support float4 attributes:
https://docs.blender.org/manual/en/dev/modeling/geometry_nodes/attributes_reference.html#attribute-data-types

The closest supported data type is Color (RGBA).

So it seems that the issue you encountered is more of a current limitation of Blender rather than a bug.

Perhaps @deadpin or @makowalski can provide some insight into this issue.
