[css-overflow-3] Does block-level box's margins contribute to scrollable overflow? #8660
Description
The spec indicates that end-side padding should be added to scrollable overflow (As per issue #129), but is explicitly undefined on the matter of adding margin areas of any box other than flex or grid items. On the other hand, scrollable-overflow-padding WPT test explicitly includes the margins of a block box to the test.
Should the spec be updated to match this behaviour?
