How can I get Matlab R2016a to show hidden surfaces?

Creating a 3D array and slicing it with transparent surfaces is a possible volume visualization as of MATLAB R2014a. In R2016a, however, densely packed surfaces are shown as empty except for the surfaces at the outside. I assume there is a link between the new graphics system introduced in R2014b.
Would it be possible to reproduce the behavior of R2014a in R2016a?
% code example:
[x,y,z] = meshgrid(-1:0.01:1);
v = exp(- x.^2 - y.^2 - z.^2);
sl = [-1:0.1:1];
h = slice(x,y,z,v,sl,sl,sl);
shading interp
set(h,'FaceAlpha',0.1)
R2014a:
R2016a:

Try changing the value in
set(h,'FaceAlpha',0.1) ;
I think for ~0.5 both figures are same.

While it might look increasingly similar, it will not lead to the same effect. "Hidden" surfaces are presented as zeros in the newer MATLAB release.
