Desktop items are vertically misaligned (shifted) when I move them after I choose to auto-hide panel

 * Cinnamon version: Cinnamon 5.2.7
 * Distribution - Mint 20
 * 64 bit

Issue

when I arrange desktop items with panel always shown, then choose to auto-hide panel, and then re-arrange one item on desktop, that item will be vertically misaligned (shifted)

Steps to reproduce

• Go to panel settings
• Change panel visibility to "Always show panel"
• Arrange your desktop items
• Open panel settings again and choose "auto-hide panel"
• Try to move one item on desktop
• The item is misaligned vertically (shifted)

Expected behaviour

The moved item should be still aligned with other desktop items.

Notes

I think this vertical shift is dependent on the panel width, My panel width is 30.
