A macro whose expansion contains itself after an unknown command,
e.g. `\def\small{\@setfontsize\small\@ixpt{10}}`, was expanded
again and again at the same position, each time in a fresh call
to doMacros, so the existing depth check never triggered and
pandoc hung. We now track consecutive expansions of the same
macro at the same position and raise PandocMacroLoop after 1000.
Closes #11088.
