And though the bug report has helped in cleaning up that instruction, I
doubt if the flags must be the same after and before a SUB instruction.
A SUB instruction affects the Accumulator content (a "result" is
generated). hence will affect the S, P flags as well. So partially
fixing bug with a commit.

If any discrepancy with my explanation feel free to shoot as always.
