Attaching an EventTrigger component to the Template`s Item GameObject causes the ScrollRect to not be scrollable via the mouse
How to reproduce:
1. Create a new project
2. In the Hierarchy Window, create a Dropdown UI element and in its Inspector add 5 new options
3. Go to the Item GameObject under Dropdown > Template > Viewport > Content > Item
4. Add the EventTrigger component to it
5. Enter Play Mode, open the dropdown and try to scroll using the mouse wheel
Expected result: the list is scrolled without any issues
Actual result: the list isn't scrollable using the mouse wheel anymore, scrolling using the scroll bar works as expected
Reproduced in: 2019.2.0a5, 2019.1.0b3, 2018.3.6f1, 2017.4.20f1
Note: Using a custom Script that implements the EventHandler Interfaces can be used as a workaround
