Automatic update from web-platform-tests Never let a non-zero-size pixel snap to zero size The logic for LayoutUnit::SnapSizeToPixel maps the size to the closest pixel align edge given a location. When a size of width less than 1 happens to straddle a pixel aligned edge this forces the size to zero. Force the size to always be non-zero if the input size is non-zero, and change PhysicalRect to use the LayoutRect snapping to get correct cull rects.
