Consider the following example:
\usemodule[tikz]
\usetikzlibrary[graphs,graphdrawing]
\starttext
\starttikzpicture
\graph { A -> B };
\stoptikzpicture
\stoptext
While it works in LaTeX (with the patch from Fresh install of TL2018: no tikz graph drawing libraries found applied), it does throw an error when loading the TikZ library in ConTeXt:

Question: How to solve that (applying the same patch as in LaTeX does not help)?
