Table section paints table col's background on its display item, so when table col's background changes, we invalidate all table sections. See https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/paint/table_paint_invalidator.cc?rcl=597a899086d4baebb543eb55b7bd283a3b2068a1&l=43 Now let LayoutObject::BackgroundChangedSinceLastPaintInvalidation() be initially true, so that a new col will be treated as background changed.
