The computed scroll-snap coordinate values seem off, perhaps by the size of the scrollbar.

This is almost certainly due to the scrollbars used in the test system. They are always shown, and take up a non-trivial chunk of the view. So I think these values are actually expected.

Created attachment 252533 [details] Screen shot of the tests (showing scrollbars) This screenshot shows what the tests look like during runs. The horizontal/vertical scrollbars effectively halve the size of the region used for display, so the snap points are calculated using that smaller size. In this case, since scrollbars are are persistent and non-trivial in size, they have a significant impact on the layout.

Works as intended.
