Error thrown when headers below level are present

[alexkwolfe]

When rendering a document with headers that are below the specified level, an error is thrown. The below example illustrates the problem.

If the # Title declaration is removed, the error is no longer thrown. So it appears that headers below the specified level cause this error.

markdownIt = require('markdown-it')

content = """
# Title

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

## Sub Title

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

### Sub Sub Title

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
"""

rendered = markdownIt()
  .use require('markdown-it-anchor'), level: 2, permalink: true
  .render(content)

console.log rendered

Hi, thank you for reporting this, and sorry for the late reply!

This is a bug due to the permalink renderer being called for all headers regardless they match the level requirements.

Fixed with 2.2.1.

No need to apologize! Thanks so much for all the work you've done on this module. 👍
