Recurse selection was not restricted to "mouse over icon" during range selection (i.e. if we shift- double click on any area of tree element, resurse select is still executed, which is wrong) Also did a bit cleanup to use existing `is_over_icon` instead of calling `outliner_item_is_co_over_icon` multiple times Pull Request: https://projects.blender.org/blender/blender/pulls/118556
