Issue with Number settings for individual header. Uncaught RangeError: once ID must not be empty or contain spaces

1.x is no longer supported

Please adjust MR to merge to 2.0.x

@joseph.olstad, I just tested version 2.0.0 and can confirm that the issue has been fixed in 2.0.0 branch.

@mrinalini9, this is the code from the 2.0.0 branch:

  Drupal.behaviors.tocTypeOptions = {
    attach(context) {
      once(
       'toc-type-header-change',
        '.js-toc-type-options-header-min, .js-toc-type-options-header-max',
        context,
      ).forEach((el) => {
        el.addEventListener('change', toggleHeaders);
      });

      toggleHeaders();
    },
  };

The Once ID (toc-type-header-change) has already been provided. So, I guess, the merging won't be required. If not, please let me know if anything to be done from my side.

Requesting the maintainers to close and mark the issue as fixed :)
