Hi everyone,
I posted a question on tex.SE with the subject as title. In short,
there is a difference in how pdflatex and lualatex handle the expression
$\left(a\mathrel{}\middle|\mathrel{}b\right)$. Using pdflatex one gets
symmetric spacing around the vertical bar while lualatex produces more
space on the right. See here for the question and an explanation in the
answer:
https://tex.stackexchange.com/questions/401234/how-to-get-a-mid-binary-relation-that-grows-in-luatex
Is this a bug or intentional behavior?
Best wishes,
