If post has a long title it's getting very hard to edit it. The title occupies all the space in the header so button `Update` isn't visible:
To my opinion title should be laconic so its length has to be restricted.
Alternatively, header can be truncated with additional dots like it is currently implemented for item in posts list.

Though I think you are right a title should be short and to the point, I don't think the answer is a short length restriction — instead (like everything else in a post), it can be community-edited to meet the preferences of the particular community.

This, on the other hand, is definitely a bug! I fixed it and very long titles now truncate in the header rather than hiding the update button.
