I edited the body and tags of [this question][1]. After I saved my changes, I realized that I forgot to add an Edit Summary. Since I was within the 5 minutes grace period, I just went back to the question, clicked on edit, added my summary and saved it.

But my summary wasn't saved for some reason.  I repeated the steps just to be sure - with no success.

Can anyone reproduce this or am I the only one seeing this?

Why are later added Edit Summaries not saved?
