Notes:
- The issue performs independently to the Package Version, rather issue appears based on the Editor version
- First touch seems to only select the button or slider
- This issue is not present in the Editor
- In the Input Action Asset (Touch.inputactions) → UI → Click → touch*/ [Touchscreen] → Interaction is set to PressOnly
- Old Input System does not seem to have the same issue
