Sort broken in Drupal 11 / jQuery 4

Problem/Motivation

The Tablesorter jQuery plugin is broken in Drupal 11 / jQuery 4. It produces an error in the console: TypeError: $.trim is not a function. (In '$.trim( val )', '$.trim' is undefined). This trim function has been removed in jQuery 4. The error makes it no longer possible to sort items in a sitemap by clicking a column header.

Steps to reproduce

On Drupal 11, install this module and create a sitemap. Ensure "Include a stylesheet in the sitemaps for humans." is enabled for the sitemap, and visit it in the browser. You'll see an error in the console and clicking the column headers does nothing.

Proposed resolution

It doesn't appear Tablesorter is actively maintained, so either choose a different method for sorting the table or modify Tablesort to remove this missing function.

Remaining tasks

Either

• An update to the current jQuery implementation

OR

• Replace jQuery Tablesorter with vanilla JavaScript
