The solution for bug #53506 added a method to pass TolX to the _qp_ function.  However, inside _qp_ it appears that the single tolerance argument is being used both for stepsize (TolX) and as a relative tolerance on the constraints (TolCon).  First, it is probably a bad idea to mix absolute and relative constraints.  Second, it is probably a good idea to be able to specify the tolerances for the main optimization problem separately for the tolerances on the constraints (Matlab has this).
