Reproducible with: 6000.0.51f1, 6000.1.7f1, 6000.2.0b5
Could not test with: 2022.3.63f1 (Assets\UI\ELEMENTS\BarElement.cs(5,2): error CS0246: The type or namespace name 'UxmlElementAttribute' could not be found)

Reproducible on:
Play Mode
Windows Standalone Player

Testing environment: Windows 10 Enterprise 21H2
Not reproducible on: No other environment tested

Notes:
- After pressing the “ESC“ key and selecting “Settings“, the opened settings tab covers the right side of the inventory, thus items there can’t be clicked even when PickingMode.Ignore is set
- Does not reproduce with other elements
