Issue ID

Regression

Yes

When clicking on overlapped UI elements the Selection order is determined not by the order in which they are rendered

uGUI

-

How to reproduce:
1. Open the attached project "case_1377544.zip"
2. Enter Scene "SampleScene" (Assets > Scene)
3. Open the Scene view
4. Enable the "2D Mode"
5. In Hierarchy window double click GameObject "Canvas"
6. In the Scene view click on a point in the red square that overlaps with all the squares under and observe the selected GameObject in the Hierarchy
7. Repeat 6th step 11 times

Expected result: The GameObject selection cycles from the top rendered element to the bottom rendered element
Actual result: The GameObject selection is determined by some other factor
