When the embedding has a number of zero eigenvalues, `λ` gets truncated. However, `U` does not, and thus `loadings` throws a `DimensionMismatch` error on master. This fixes that error. Alternatively, we could truncate `U` as well, but retaining the full `U` matrix makes it easier to obtain a full orthonormal basis, if desired.
