How to reproduce:
1. Open the attached project "1179982.zip"
2. Enter Play mode
3. Scroll through the Input Field

Expected result: Input Field's Text moves in the opposite direction to the Scrollbar
Actual result: Input Field's Text moves in the same direction as the Scrollbar

Reproducible with Unity versions: 2017.4.32f1, 2018.4.8f1, 2019.1.14f1, 2019.2.5f1, 2019.3.0b3, 2020.1.0a4
Reproducible with package versions: 0.1.2, 1.0.26, 1.1.0, 1.2.4, 1.3.0, 1.4.0, 1.4.1, 2.0.1

Notes:
Setting the Value field of the scrollbar to 1 and setting the direction to Top To Bottom works as a workaround.
To test on Unity 2017.4 and early versions of Unity 2018.3 TextMeshPro package was downloaded from the Asset Store.
