List of known issues with CSS snap points implementation:

- Rename the CSS_SCROLL_SNAP feature flag to CSS_SNAP_POINTS.

- Make WKWebView set deceleration to fast when didCommitLayerTree is called, rather than when scrolling will begin dragging.

- Account for insets on the iOS mainframe.

- Improve Mac snapping animations (also, improve their performance)

- In the spec, the repeat value begins counting from the "last point." We need to clarify what this means -- currently, the implementation starts counting from the furthest point, which would not be correct if the list of snap points is not sorted and our interpretation of "last point" is the last point specified by the user.

- Clarify what the expected behavior is when a snap point moves, disappears, or is added to the snap scrolling container.
