Issue when extending a slur over a section break
In the attached example, there is a note in measure 3 which is not joined by a slur. To extend the slur to this note, select the slur in measure 2 and press Shift + →.
Result: This only shifts the right handle of the slur slightly to the right (not an expected result). The slur is not extended to the next note in measure 3 (which would be an expected result). The portion of the slur in measure 3 has to be selected in order to properly extend the slur to the next note. You should be able to select any portion of the slur and extend it.
Also, if you select any other handle on the slur (not one of the end handles) and press Shift + →, a similar rightward shift of the handle occurs. Is this an expected result?
