Research direction
Start by locating RectDiagonal and the existing Eye multiplication behavior in FillArrays.jl. Compare the two examples in the issue and identify the expected multiplication result for RectDiagonal; done means the inconsistent operation is supported with behavior matching the shown Eye case.
