Bug Report

Please replace any of [these areas] in the paragraphs below with the requested information.

Bug Type

• Assertion Failure

Description

This specific test case was needed to trigger the behavior needed to test a branch that was previously thought of as unreachable.
When that branch assert was hit, it triggered.

Note that these defensive asserts are in the code to ensure that if we hit paths that we thought were unreachable, that we know about them instead of the branch failing in a bad way.

Specifics

What operating system and version are you running into this behavior on?

N/A

What version are you seeing this behavior in? (Run pip list or pipenv run pip list and look for the entry beside pymarkdownlnt.)

latest, main branch

Are there any extra steps that need to be taken before executing the application?

test_extra_044lc

What is the command line you invoke to get this behavior?

test_extra_044lc

Are you using a configuration file? Either on the command line or one of the implicit configuration files? If so, attach that file to this issue.

N/A

What Markdown document causes this behavior to manifest? Attach that file to this issue.

Actual Behavior

This caused the branch protection assert to be triggered.

Expected Behavior

Now that we know this branch can get hit, the assert should be replaced with proper handling of the branch conditional.
