I'm not sure if this was always the case, but I noticed this in the latest version. If I double-click on a cell and edit it and then hit Enter, the cell text still displays the old text in the pane. Only when I move the cursor away from the current cell (Either by clicking elsewhere or using cursor keys to move the highlight cell marker) does the edited cell text update with the new text.
