Set overflow: hidden for scroll snap test body
The test is flaky on Linux because the rightmost box in the line
occasionally exceeds the width of the viewport. This may be due to
calculations related to viewport width with scrollbars. Turning the
scrollbars off may help reduce flakiness. This is a speculative fix.
