Accordion Collapse All / Expand All functionality broken

Problem/Motivation

On a fresh ddev Drupal 11 install, the Collapse All / Expand All functionality is broken.

On page load the first tab is open and the 'Collapse All ' button is shown. Clicking the button opens all the tabs and the 'Collapse All ' button still shows.

Clicking the 'Collapse All ' button at this point does nothing at all.

When I close all the tabs manually by clicking on them, the 'Expand All' button is shown. When I click on this, nothing happens.

This behavior is consistent across browsers.
