The gear in composer is not working properly for Heliosurge. When clicked, the bar below animates, but the dropdown does not appear. Heliosurge has tested on mobile and found the issue to be specific to their site, as it works fine on Meta. After troubleshooting, Heliosurge discovered that the issue is related to a theme component, specifically due to incompatibility with Ember 5 mitigation and the move to Glimmer. Sam suggested trying safe mode, which led to the discovery of the issue. The problematic components are MD Composer Extras and Scrollable Post Content, both of which cause the issue when enabled.
