EventData.useDragThreshold does not get reset back to true after clicking a Scrollbar

Package: Input System

-

How to reproduce:
1. Open the user's attached project
2. Make sure the Architecture is set to "x86_64" in the Build Settings window
3. Comment out line 8 in "FixPointerDrag.cs"
4. Enter Play mode
5. Try dragging the Canvas inside it ("Like you would scroll a phone")
6. Notice the Drag Threshold is used
7. Click on the Scroll Bar
8. Try dragging the Canvas inside it ("Like you would scroll a phone")

Expected results: When the Viewport is selected, useDragThreshold is set to true again
Actual results: When the Viewport is selected, useDragThreshold is NOT set to true again and there is no Drag Threshold

Reproducible with: Input System 1.0.0 - 1.1.0-preview.1 (2019.4.16f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0a10, 2021.2.0a1)
Could not test with: 2018.4.30f1 (Errors downgrading)
Not reproducible with: Input System 1.1.0-preview.2 (2019.4.16f1, 2020.1.17f1, 2020.2.1f1, 2021.1.0a10, 2021.2.0a1)

Workaround: In the "OnInitializePotentialDrag(PointerEventData eventData)" set "eventData.useDragThreshold = true"

  1. Resolution Note (fix version 1.1.0-preview.2):

    Does no longer reproduce with Input System 1.1.0-preview.2 using Unity 2019.4 stream and above
