This version of the test succeeds:
test[MakeExplicit[ KD[ua, lb] PD[u[ub], la]], {PD[u1, 1] + PD[u2, 2] + PD[u3, 3]}]
Note that I needed to modify both input and output. I believe the expected output for the test is wrong as well.
I believe that this was fixed in 4ac728ac483c7b1a488474f87ff097905466d7eb.. 321220cf5b4ef8de0fc1a57cb679f0d2f3ff599e. Please reopen if not.
The test PD[u[ua],la] fails.
This is also a real-world problem; I have to work around this issue by contracting via KroneckerDelta outside of PD in McLachlan.
