       - Stabilised Helpdesk Dusk browser tests by adding durable Dusk selectors to settings and ticket create controls.
       - Replaced browser-test Livewire internals with real UI interactions for settings sections, Select2 controls and HTML editors.
       - Kept module.json version in sync with changelog.yaml.

+  "1.3.12":
+    changed:
+      - Fixed ticket comment submission by forcing the Helpdesk HTML editor content into Livewire before directly invoking addComment from the form submit path.
+      - Fixed nested reply submission by applying the same editor-to-Livewire synchronisation before addReply.
+      - Updated the Helpdesk browser test so comment creation must persist a real helpdesk_comments database row instead of being masked by direct Livewire component mutation.
+      - Kept module.json version in sync with changelog.yaml.
