Automatic update from web-platform-tests Enforce scroll axis constraints in single-axis containers The SingleAxisScrollContainers feature allows containers to be configured to scroll along only one axis via CSS overflow properties. Previously, scroll APIs like scrollTo and scrollIntoView did not respect these constraints and would incorrectly apply offsets to both axes. This change updates PaintLayerScrollableArea to accurately reflect single-axis scrollability. The scrollable delta for the maximum scroll offset is now set to zero for non-scrollable axes. Adds tests to ensure scrollIntoView and style changes to single-axis scroll container work as expected.
