lualatex math tables not working

I just updated MikTeX and found that a .tex file which previously created the right output under lualatex no longer does so. However, xelatex does create the correct output.

The problem seems to be that lualatex is not picking up the opentype MATH tables for stretchy symbols in the Unicode private use area. It works correctly with the standard stretchy symbols such as left{ and right}. Note that the OpnBracS and ClsBracS have the left and right baked in. Those symbols are found in the logix.otf file and the symbols are defined in logix.sty, both of which are in the logix package. Here is some test code.

documentclass[10pt]{article}
usepackage{logix}
newcommand testFrac   {frac{1}{2+frac{3}{4}}}
newcommand testFrak   {frac{frac{frac{frac{1}{1}}{frac{1}{1}}}{frac{frac{1}{1}}{frac{1}{1}}}}{frac{frac{frac{1}{1}}{frac{1}{1}}}{frac{frac{1}{1}}{frac{1}{1}}}}}

begin{document}
   $ OpnBracS testFrac ClsBracS $ hspace{2em} $ OpnBracS testFrak ClsBracS $
   end{document}

This is the output from xelatex

And here is the output from lualatex
