Comma separated selectors list limits usability

This split was necessary to imitate the :visible selector not available in VanillaJS.

We can also likely change this split with a bit more complex code and avoid breaking compatibility.

something similar to

splitSelectors: function (selector) {
  const result = [];
  let current = '';
  let depth = 0;

  for (let i = 0; i < selector.length; i++) {
    const char = selector[i];

    if (char === '[' || char === '(') {
      depth++;
    }
    else if (char === ']' || char === ')') {
      depth = Math.max(depth - 1, 0);
    }

    if (char === ',' && depth === 0) {
      if (current.trim()) {
        result.push(current.trim());
      }
      current = '';
    }
    else {
      current += char;
    }
  }

  if (current.trim()) {
    result.push(current.trim());
  }

  return result;
},
