Edits in auto-saving editors are kept
Some editors save as you go rather than behind a Save button — the ones that edit a page or a code file directly. On the React and mobile front-ends those edits went nowhere. The text stayed on screen, nothing reported a problem, and the work was gone the next time the view loaded.
They now write back the way the main portal does: a short pause in typing saves the text, a burst of keystrokes becomes one save, and anything still unsaved is written out when you navigate away.
