[New Input System] Tapping the Scroll Bar makes it jump to the bottom, not the selection

Package: UGUI


Reproduction steps:
1. Open "1193571" project
2. Enter Play mode
3. Tap in the middle of the Scroll Bar

Expected Result: The Scroll bar jumps to the selection
Actual Result: The Scroll Bar jumps to the bottom

Reproduced with: 2020.1.0a9, 2019.3.0b8, 2019.2.10f1, 2018.4.12f1
Did not reproduce on: 2017.4.33f1 (No Packman)

  1. Resolution Note (fix version 1.0.0):

    Fix issue with Scrollbar::ClickRepeat that was using the same PointEventData over multiple frames. This is a issue in the new input system as it uses a single PointerEventData for every point modifying data where necessary where the old system has a PointerEventData for each pointer.

    Modifying the code such that it uses the same data from the PointerEventData each frame instead of the PointerEventData itself solves the issue. I see no reason why the 2 points of data pointerPressRaycast.screenPosition and eventData.enterEventCamera would ever need to be changed between the frames where the pointer is down.

    Please note that this fix requires an update to the Unity editor as well, not just the package. More details on the forum thread:
