Wrong no-multiple-space-atx warning if atx heading is followed by a badly shaped <pre>-block

[arwedus]

Overview

This is an example for using <pre> tag instead of markdown code blocks notation.
No idea why someone would do it but it leads to an error in pymarkdown parsing.
It's a rare case and I think that the fact that we stumble upon such edge cases is a good sign showing the overall quality of pymarkdown, so thanks for that 👍🏼 .

Setup

Installed python packages:

application_properties==0.8.2
pymarkdownlnt==0.9.16
pyyaml==5.4.1.post0  # constraint

Command line:

pymarkdown -c pymarkdown.json scan readme.md

The file that causes the error:

readme.md

The error message is:

readme.md:29:1: MD019: Multiple spaces are present after hash character on Atx Heading. (no-multiple-space-atx)
