When creating a new topic in a category that requires approval, the composer wou…ld show a "discard draft" modal on every subsequent attempt to open it (new topic or reply). The issue was in the post-enqueue handler in the composer service. After a post is enqueued, the code tries to push the pending post into `this.topicController.model.pending_posts`. When creating a new topic, the user is on the topic list — not viewing a topic — so `this.topicController.model` is undefined. Accessing `.pending_posts` on undefined throws a TypeError, which prevents `destroyDraft()` and `close()` from ever executing. The composer model stays on the service with dirty content, so any subsequent composer open triggers the discard draft modal. The fix adds optional chaining (`?.`) so the pending_posts push is safely skipped when no topic model is loaded. https://meta.discourse.org/t/397711
