Today, I edited two posts that were shown in the "Low Quality Posts" page for the new review system. After I clicked on "Save Edits," I was asked if I wanted to leave the page, or stay on that page. Thinking it was a revival of a bug that was reported before, I clicked on "Leave page," and I was redirected to the page showing the question, with the edited post highlighted.
I noticed this only today. Before, I was not redirected to other pages, when editing low quality posts.
The edits I have done were saved, though. It is just a matter of being redirected to a different page when it is not supposed to happen.
