Escaping "#" at the end of heading

[Djordjenp]

Hello I looked into your library and I found if we pass string like "# Hello World \#" we get back header with text token "Hello World" so escaping hash is skipped because of this line in "heading" tokenizer:

  const tmp = state.skipCharsBack(max, 0x23, pos) // #

Is this how it's suppose to work because when I passed same string to "commonmark" demo, it got rendered like "Hello World #"

the output looks the same to me:

$ echo -e '# Hello World \#' | deno run --allow-read npm:[email protected]
<h1>Hello World #</h1>
$ echo -e '# Hello World \#' | deno run --allow-read npm:[email protected]
<h1>Hello World #</h1>
