Bug: Inconsistency in row_contents_component drop down feature

[malchua]

Currently, we are allowed to share a group along with an ancestor or descendant of that group, like the following:

Subgroup 12 A is being shared, along with it's parent group Group 12. This causes a UI error, where you are unable click on the dropdown arrow for the lower Subgroup 12 A to expand it, if the higher Subgroup 12 A is visible.


If the top Subgroup 12 A is not present, then the dropdown for the lower Subgroup 12 A works as usual.
