TMP_InputField Vertical Scrollbar sometimes snaps to the top when value of "1" is assigned

Package: TextMeshPro


How to reproduce:
1. Open attached "" project and Scenes/SampleScene scene
2. Enter the Play mode
3. Select the Input field that is on the bottom in the Game view
4. Enter any text and press Enter
5. Keep repeating step #4 and observe the Scrollbar of the Input field that is above

Expected result: Scrollbar is positioned at the Bottom
Actual result: Scrollbar sometimes snaps to the top

Reproducible with: 2019.4.9f1, 2020.1.4f1, 2020.2.0b1 (TextMeshPro 2.0.1 - 3.0.1)
Could not test with: 2018.4.27f (could not downgrade)

  1. Resolution Note (fix version 3.0.3):

    Made several improvements to the Input Field with respect to handling and behavior when a scrollbar is used.

    The input field now appears to be behaving correctly with the provided user project and without any modifications. I would still recommend using the revised code I provided to the user but both will now work as expected.

    The fix for this issue will be included in the next release of the TMP package which is expected to be version 1.5.2 for Unity 2018.4, version 2.1.2 for Unity 2019.x and version 3.0.2 for Unity 2020.x.
