I don’t know whether this is a bug or on purpose but the title fields on stackexchange.com and all their forums, when writing a new post, is not being checked by LT.org (2.0.28) in FF (the latest version), Windows10 (all updates to the present day).
Thanks for your report. Could you send a screenshot? Title fields are usually one-line fields and those are not checked on purpose. Checking the multi-line fields works for me.
Confirmed, the body text section works fine. Good to know that the title field is disregarded on purpose.
