Reviewed by Alan Baradlay.

While ideally absolute positioned object with static position would stick to its line when paginated
(it does in Chrome) we don't implement this in legacy either. As a result there is nothing to here.

* LayoutTests/fast/multicol/content-bounding-box-rtl.html:

The new expected result here is logically more correct (or equally wrong in practice) compared to legacy.

* Source/WebCore/layout/integration/LayoutIntegrationCoverage.cpp:
(WebCore::LayoutIntegration::printReason):
(WebCore::LayoutIntegration::canUseForChild):
(WebCore::LayoutIntegration::canUseForLineLayoutWithReason):
* Source/WebCore/layout/integration/LayoutIntegrationCoverage.h:
