Saving edit no edits made still causes draft to be shown

When editing another user’s post, but not making any edits, and clicking Save edit, what happens is very unusual. Although the post doesn’t seem to have made edits and you have closed the edit box (as you have pressed the Save button), under your drafts, the post is still there.
This is inconvenient as re-visiting the topic opens up the edit box again, and even when clicking the Save button to close it, it still shows as a draft. And the cycle repeats.


This is weird and I can reproduce the issue here on Meta! thanks for reporting it.
