dot([2+i,i],[9-i,7]) returns 19+14*i, just like it does in Home.

I suppose if we were to be truly technical, then both the Prime and Wolfram would be incorrect in allowing vectors that are not real-valued since the "dot product" (being a special type of inner product) is for finite Euclidean spaces. Both Maple and Matlab disagree with Wolfram Alpha; their "dot" product uses the Hermitian inner product if the vectors are complex.
