Last week the [retag] button was removed and its functionality was merged with a smart [edit] button. This smart feature decides itself what has been edited and applies tag edits immediately or puts edit into edit queue if user has enough reputation for former but not for the latter.
I noticed however that [Save Edits] button requires the edit summary field to be at least 10 characters long. However, if you fill in those 10 characters your text is then replaced with generic 'edited tags'.
This behavior is counter-intuitive. If the user enters edit summary it should be kept. If the summary is always filled with generic description, then user should be able to save edits without filling in "Edit Summary" text.
Is this a bug, or does it behave as intended?
