CSS issue (scroll bar appearing) with row small margin and row small spacing

[bassmartin]

When using regular spacing, no scrollbar is appearing :

ResponsiveRow row = layout.addRow().withMargin(ResponsiveRow.MarginSize.SMALL).withSpacing(true)
row.addColumn().withDisplayRules(12, 12, 6, 6).withComponent(panel1)
row.addColumn().withDisplayRules(12, 12, 6, 6).withComponent(panel2)

result :

When using small spacing, a scrollbar is appearing :

ResponsiveRow row = layout.addRow().withMargin(ResponsiveRow.MarginSize.SMALL).withSpacing(ResponsiveRow.SpacingSize.SMALL, true)
row.addColumn().withDisplayRules(12, 12, 6, 6).withComponent(panel1)
row.addColumn().withDisplayRules(12, 12, 6, 6).withComponent(panel2)

Result :

Using only horizontal spacing (with small margin) : no scrollbar
Using only vertical spacing (with small margin) : scroll bar

Thanks.
