The topic discusses a bug where the post number in the topic timeline is initially blank when loading a topic, and only appears after a delay. NateDhaliwal first reported the issue, noting it occurs on both mobile and desktop, and affects both short and long topics, with a screenshot provided post #7. NateDhaliwal further theorizes that the problem occurs when not entering a topic through the last reply [post #8](/t/-/372881/8].
Sam explains that the behavior is by design, with a debounce intended to only inject the history after browser settling [post #2](/t/-/372881/2]. Sam states the code was recently ported to Ember, but the issue appears consistent with past behavior [post #2](/t/-/372881/2]. Despite requests for clarification from NateDhaliwal about expected behavior [post #4](/t/-/372881/4], Sam is unable to reproduce the bug [post #6](/t/-/372881/6, #9](/t/-/372881/9). The issue was also reported on Meta [post #1](/t/-/372881/1].
