[issue45333] += operator and accessors bug?

[chovey]

chovey <chovey at sandia.gov> added the comment:

I confirm I do get this error:
Exception has occurred: _UFuncOutputCastingError
Cannot cast ufunc 'add' output from dtype('float64') to dtype('int64') with casting rule 'same_kind'

I next will paste a minimum working example.
