On chat faq there are some topics which is expandable (i.e has
show more link) which have arrow ▶ at title end which indicates something like that post is expandable but there are two topics "How do I talk?" and "How do I format my messages?" that are expandable, also has
show more link but misses the arrows ▶ at the end of title.
Note: This is not (Don't consider it) a serious issue or problem, I've just discussed it for improvement. I'm not expecting any priority give to this fix
