We fail several cases in the WPT test `scroll-animations/view-timelines/sticky/view-timeline-sticky-offscreen-7.html`: ``` await runTimelineRangeTest(t, { rangeStart: { rangeName: 'contain', offset: CSS.percent(0) } , rangeEnd: { rangeName: 'contain', offset: CSS.percent(100) }, startOffset: STATIC_START - ROOM_ABOVE + VIEWPORT_HEIGHT, endOffset: BIG_TARGET_STATIC_END + ROOM_BELOW - VIEWPORT_HEIGHT, axis: 'block' }); await runTimelineRangeTest(t, { rangeStart: { rangeName: 'entry', offset: CSS.percent(0) }, rangeEnd: { rangeName: 'entry', offset: CSS.percent(100) }, startOffset: STATIC_START - ROOM_ABOVE, endOffset: STATIC_START - ROOM_ABOVE + VIEWPORT_HEIGHT, axis: 'block' }); await runTimelineRangeTest(t, { rangeStart: { rangeName: 'exit-crossing', offset: CSS.percent(0) }, rangeEnd: { rangeName: 'exit-crossing', offset: CSS.percent(100) }, startOffset: STATIC_START - ROOM_ABOVE + VIEWPORT_HEIGHT, endOffset: BIG_TARGET_STATIC_END + ROOM_BELOW, axis: 'block' }); ```

For failing test number 1 we should operate on a [600-1050] range but operate on a [950-1050] range. For failing test number 2 we should operate on a [100-600] range but operate on a [100-950] range. For failing test number 3 we should operate on a [600-1550] range but operate on a [950-1550] range.
