Custom parser duplicates the input content on web

[Skalakid]

Description:

After applying custom parser function to the Live Markdown Input, its content breaks.

For example, after applying following parser:

function parser(input) {
  'worklet';

  const ranges = [];
  // Regular expressions for hashtags and mentions
  const hashtagRegex = /#(\w+)/g;
  const mentionRegex = /@(\w+)/g;

  // Find and push hashtag ranges
  let match;
  while ((match = hashtagRegex.exec(input)) !== null) {
    ranges.push({
      start: match.index,
      length: match[0].length,
      type: 'link', // type 'link' for hashtags
    });
  }

  // Find and push mention ranges
  while ((match = mentionRegex.exec(input)) !== null) {
    ranges.push({
      start: match.index,
      length: match[0].length,
      type: 'mention-user', // type 'mention-user' for user mentions
    });
  }

  return ranges;
}
