Reference Not Found Error

[tkurtbond]

When I process the following reST file (notice it the whole file is indented 3 spaces)

   **Option:** Arachnaurs' webs are made with a neurotoxin_ that can
   quickly paralyze their prey!  When wrapped in a web, make a Vigor
   roll or quickly lose consciousness.

   .. _neurotoxin: https://www.sciencenews.org/article/spiders-poisonous-webs-neuro-toxins-genes

into ms or PDF via ms output with the command

pandoc -s -r rst -w ms -o rnf.ms.pdf rnf.rst

I get the errors

[WARNING] Reference not found for 'neurotoxin' at chunk line 1 column 57
<standard input>:70: macro error: pdfhref has no destination

and the resulting output PDF file and .ms file indeed do not have the link.

Here's the .ms file that was generated:

I'm using the following version of Pandoc:

pandoc 2.10.1
Compiled with pandoc-types 1.21, texmath 0.12.0.2, skylighting 0.8.5

My OS information is:

Mac OS X, Version 10.15.6, Build 19G73

If you unindent it, it will work.

Looks like we're wrongly assuming that the reference definitions will be unindented.
