allow insert Measure, VBox, or HBox before a VBox or HBox
My feature request (https://musescore.org/en/node/78341) was approved, so I'm copying here into issue tracker:
...Musescore won't let me insert a Measure, VBox, or HBox before a VBox or HBox.
Selecting a V/H Box and pressing insert button on keyboard or double clicking a V/H Box or Measure from palette, or dragging & dropping a V/H Box or Measure from palette onto the V/H Box...all result in the V/H Box or Measure being appended to the end of my score.
But I want the V/H Boxes and Measures to be inserted before the V/H Box.
