Flickering hover state in ListView using new Input System

Package: UI Toolkit

-

Description:
The ListView gives hover feedback by default. When using the new Input system, which changes the behaviour of the Event System, one can observe the issue described below.

Steps to reproduce:
1) Create a project and reference com.unity.ui@1.0.0-preview.7 and com.unity.inputsystem@1.0.0
2) Open the Sprites scene
3) Enter playmode

Observed:
As the mouse moves up and down, the hover state flickers between the actual element under the mouse and the first element

Expected:
As the mouse moves up and down, the hover state should only follow element under the mouse

Note: behaviour is correct with old input system.

Unity version: 2021.1.3f1

    Just want to mention that this issue does not only happen for ListViews, instead it happens for all VisualElements, so unfortunately the whole UI is affected by this bug
