Reproduction steps:
1. Open the user's project "TestProject.zip" and open the "New Scene" Scene
2. Play the Scene
3. With the left mouse button drag the slider (but don't release)
4. Now also hold the right mouse button (mouse cursor becomes Locked)
5. Release the left mouse button
6. Release the right mouse button (mouse cursor becomes Unlocked)
7. Move the mouse around

Expected result: the dragger is not following the mouse position
Actual result: the dragger is following the mouse position

Reproducible with: 2021.2.7f1, 2022.1.0a11
Not reproducible with: 2022.1.0a12, 2022.1.0b2
Could not test with: 2019.4.34f1, 2020.3.25f1 (project could not be converted to these versions)

Notes:
- After the 7th step pressing the left mouse button makes the dragger stop following the mouse position
- CursorHidder Object contains a "CursorHider.css" script which makes the mouse cursor Locked when the right mouse button is pressed down
