marked is incompatible with Safari on iOS/iPadOS prior to 16.5 due to a SyntaxError.

The issue stems from two instances of RegExp negative lookbehind assertions (?<!...) within the blockSkip constant.

These appear to be the only instances of this incompatible syntax in the entire codebase. Because the issue is isolated to this single constant, a targeted fix could restore compatibility for a large number of users.

The problematic lines are within the link and code replacements:

const blockSkip = edit(/link|code|html/, 'g')
  .replace('link', /\[(?:[^\[\]`]|(?<!`)(?<a>`+)[^`]+\k<a>(?!`))*?\]\((?:...)\)/) // <-- OFFENSE #1
  .replace('code', /(?<!`)(?<b>`+)[^`]+\k<b>(?!`)/)                                // <-- OFFENSE #2
  .replace('html', /<(?! )[^<>]*?>/)
  .getRegex();

Thank you for your consideration and for maintaining this library.
