[Possible Bugfix] FieldIds > 99, breaking conditional logic

I have a form with ~150 fields on it and using this repeater fields plugin.

When I change any fields with an Id that is 3 digits or more, it does not trigger the conditional fields, and the console has an error coming from “wp_repeater.js” line 42 saying “ids.shift() is not a function”

function yeeaddons_gf_get_input_id_by_html_id(htmlId) {
  var ids = yeeaddons_gf_get_ids_by_html_id(htmlId);
  var id = ids[ids.length - 1];
  if (ids.length == 3) {
    ids.shift();
    id = ids.join(".");
  } else {
    return ids;
  }
  return id;
}

Looking at the code, it looks like its expecting ids to be an array, but atleast with my testing, ids is a string. So should the if statement not read like:

if (Array.IsArray(ids) && ids.length === 3) {

Just to clarify as well, these fields that are breaking are not even inside a repeater, and other fields with lower Ids are still working fine with conditionals.

Please let me know what you think
