Describe the bug
highlight-line-numbers causing commented code on uncommented code

To Reproduce
Steps to reproduce the behavior:

1. I'm developing nextjs app
2. importing highlight.js lazy loading using NodeJS import()
3. importing highlightjs-line-numbers.js lazy loading using NodeJS
4. calling hljs.highlightBlock then hljs.lineNumbersBlock
5. first render is no problem
6. if the component did re-render, which also calls again hljs.highlightBlock and hljs.lineNumbersBlock it broke the highlighting

** Problem **

• code that is not a commented recognized as comment
• happens on any code language

Expected behavior
highlight-line-numbers should not modify highlighting done by highlight.js for the subsequent calls

Additional context
I know I can prevent re-calling the method by tracking if it has been called or not. But I also have cases when this is not possible.
