#41625: Logic for detecting expanded Text and Media widgets is
inconsistent/unreliable

--------------------------+-----------------
 The Text widget and Media widgets in 4.8 defer to initialize their JS
 fields until the widget fully expands since the JS logic needs the
 element's dimensions to be finalized to initialize properly. The current
 logic for detecting the completion of the animation is faulty in that it
 is looking at the wrong element for the `:animated` pseudo-class and it
 also should be using the `open` class instead, the latter which is not
 properly getting set for widgets in the Customizer.
