💡 Background and solution

I was customizing theme with menu item's itemMarginInline to be 0, then I found that the icon is not centered when the menu is collapsed.

It seems like the paddingInline calc logic caused this bug. Don't know why using fontSizeSM here, cause any other font here is LG. The correct calc logic should be calc(50% - ${fontSizeLG / 2}px - ${itemMarginInline}px)
