Instead, grab it from hoveredRow, since almost always (with only one exception) this is where the edit control has to be shown. This makes it much easier to adjust views, e.g. add a new editable field in the middle of configuration view, because it's not necessary to manually change and test all the indexes below the row being changed. Additionally, it removes a lot of awkward and opaque row calculations.
