It "works" with 6.3.beta4. And it fails with #13246 applied to 6.3.beta4.
But there is a reason why it fails with #13246 applied and "works" without
it. The plot has only three data points. So, #13246 is doing its job just
as it was intended to I suppose :-)
sage: var('n,a')
sage: hbar, m = 1,1
sage: psi(x,t,n)=sqrt(2/a)*sin(n*pi*x/a)*e^(-i*n^2*pi^2*hbar*t/(2*m*a^2));
sage: print psi
sage: Psi(x,t)=1/sqrt(2)*psi(x,t,1)+1/sqrt(2)*psi(x,t,2);
sage: print Psi
sage: P(x,t,a) = Psi.conjugate()*Psi
sage: print P.expand()
sage: p = plot(P(x,1,1),x,0,1)
sage: po = p._objects[0]; po.xdata
[0.0,0.5,1.0]
