Unlike its non-region siblings, the box-shadow and the outline of a composited nested region is clipped.
This is visible when the margin of the nested region is smaller than the size of the box-shadow or of the outline.
You can see this in https://trac.webkit.org/export/157780/trunk/LayoutTests/compositing/regions/region-as-layer-in-another-flowthread.html if you lower the margin-left to be less than the size of the box-shadow or the size of the outline.
