Spin-off from #2988431: [Meta] Accessibility plan for Media Library Widget.
Problem/Motivation
After clicking the hide/show weights link I am not sure what happened.
This was noted in testing of the show/hide media item weights for the MediaLibraryWidget.
However it applies equally to the row weights on draggable rows, so it would be good to improve both of those at once, and keep them consistent with one another.
