Scrollbar Value and Size sliders are broken when the Canvas has a CanvasScaler Mode set to 'Scale With Screen Size'
How to reproduce:
1. Open the attached "ScrollRectWithCanvasScaler.zip"
2. Expand 'Canvas_Root', 'Scroll View' Game objects
3. Click on 'Scrollbar Vertical' or 'Scrollbar Vertical' and try to move the sliders of 'Scrollbar (Script)' component's 'Value' and 'Size' parameters to values between 0 and 1
4. Enter to Play mode and observe Inspector
Expected result: All Scrollbar parameters have a fixed value
Actual result: 'Value' and 'Size' parameter's values are changed to '0' or '1' or sliders are moving by their own
Reproducible: 2017.4.24f1, 2018.3.10f1, 2019.1.0b8, 2019.2.0a9
Can't reproduce: 2018.3.0a1, because ScrollRect.value is NaN
Notes:
- The bug is also reproducible when CanvasScaler Mode set to 'Constant Pixel Size'. Reproducible on 2018.3.10f1
- The 'Value' and 'Size' sliders aren't movable in 2017.4.0f1, 2017.4.24f1, 2018.3.0a2, 2018.3.10f1 Unity versions
