The tooltip for
Reject and Edit says
reject this suggested edit and provide a new edit... which appears to be a perfectly valid response and reads to me as
reject the edit, then let me
edit the original post (else if I was happy with the edit minus a slight tweak - then I'd have clicked
improve - which I'd expect to fail me in this case). I expect if you'd just rejected it (it is after all automated vandalism), you'd have passed and been able to edit it afterwards. I'd say that either the button is broken, or it's just misleading as to what it actually does vs implies it does... —
