I've now switched to using PageHeadSections for this, and am
experiencing much the same issue. If I insert something before the
current index I need to add 1 to the selected index to compensate, and
the reverse for removal.

** Summary changed:

- Picker: selectedIndex changes incorrectly when removing model entries
+ PageHeadSections/Picker: selectedIndex changes incorrectly when inserting/removing model entries

Title:
  PageHeadSections/Picker: selectedIndex changes incorrectly when
  inserting/removing model entries

Status in ubuntu-ui-toolkit package in Ubuntu:
  Triaged

Bug description:
  I've attached a minimal program to demonstrate the problem.

  The Model contains 20 items, and the selectedIndex is at 18.
  Clicking the button below will remove the item at index 10.
  Expected behaviour:
    Picker keeps number 18 selected.
  Actual behaviour:
    Picker jumps to number 9, the index before the one just deleted.

  Observe that when changing the button code to remove index 3 instead
  of 10, the picker works correctly, and remains at item 18.

  The behaviour only breaks on some index removals.

  inserts appear to behave correctly.
