converter.makeHtml is slow for multiple dashes terminated with extra characters

[rolandliwag]

const converter = new require('showdown').Converter();
return converter.makeHtml('- - - - - - - - - - - - - - - - - - - - - - - - - - - - A');

The extra characters in this case are an nbsp (char code 160) and the uppercase A. Adding more dashes to the left makes it take more and more time.

#312 partially fixed this since the output is now correct but it is still slow.

I've narrowed the problem (and found the culprit) but I'm really not sure how to fix it. In fact, I don't even know why it is so slow.

I've opened a question in codereview, asking for help. Maybe the collective knowledge can find an answer or, at least, shed some light on this strange behavior.

Should be fixed now.

Thanks again.
