wrong selection with mouse from right to left

With the exemple from 2.0 from yesterday. (I first wanted to try transposition but discovered that)

1 add two mesure before measure 7
2 Change measure time to 5/4
3 select the notes in new measure 9 notes
4 copy and past
5 select from right to left : first note the E at the right, and second note the F in the left (that are in fact first and last note inversed)
6 paste in the other empty measure
7 last note E isn't copied and that is a silence insted
