Below I provide ECM for LaTeX cross-referencing you requested, which itself
summarizes the issues in the current export engine: We see that there are
mix of results for different cases of heading title (i.e., \texttt{},
\hyperref[]{}, & \ref{}) and that only referring by custom_id results in a
correct cross-reference. Note that, as mentioned in the list several time
before, there is currently no way to customizing hyperref format using
'org-export-latex-hyperref-format' varible, which becomes obsolete now.
