<p>Session Limit's <code>\Drupal\session_limit\Services\SessionLimit</code> class currently type-hints the default <code>ModuleHandler</code> class instead of the interface. This prevents custom overrides of <code>ModuleHandler</code>, for example by <a href="https://www.drupal.org/project/hux">Hux</a> and <a href="https://www.drupal.org/project/hook_event_dispatcher">Hook Event Dispatcher</a>.</p>

<p>Updated Hook Event Dispatcher from <a href="https://www.drupal.org/project/hook_event_dispatcher/releases/3.2.0">3.2.0</a> to <a href="https://www.drupal.org/project/hook_event_dispatcher/releases/3.3.1">3.3.1</a>, now getting fatal errors like this:</p>

<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>Install Hook Event Dispatcher 3.3.0+ after installing any module that injects the <code>module_handler</code> service with the parameter being type-hinted to the core <code>ModuleHandler</code> class instead of <code>ModuleHandlerInterface</code>. This should result in a similar fatal error to the above. The module in the error is <a href="https://www.drupal.org/project/session_limit">Session Limit</a>, and the error causing parameter can be found in <a href="https://git.drupalcode.org/project/session_limit/-/blob/c4b34d26cf8ebbae7bab342c4d2b56f8f6fc6778/src/Services/SessionLimit.php#L119"><code>Services/SessionLimit::__construct()</code></a></p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Change type-hint from the default service implementation <code>\Drupal\Core\Extension\ModuleHandler</code> to the interface <code>\Drupal\Core\Extension\ModuleHandlerInterface</code>.</p>
