Converted focusedImageIndex assignment to ternary and general cleanup

* Transaction fix (#4421)

* When transaction is active, objects.get should search in dirty object first.

Co-authored-by: Andrew Henry <akhenry@gmail.com>

* find insert location prior to adding item to tree

* no need to resort

add item should only add to direct descendants

* remove unused function

* copy composition before sorting

* remove unused var

* remove master pollution

* Revert "remove master pollution"

This reverts commit 93bee13915.

* add item to correct location
