This is similar to bug 1641139 but may need more investigation, thus spawned out.

As shown in the testcase, when the ruby text serves as the containing block, the absolutely-positioned element is slightly higher than the text, this might be a conforming behavior, but it seems to be different from what Blink does so we may have problem in the future.

When the ruby text container serves as the containing block, however, the absolutely-positioned descendant doesn't render. This can be easily fixed by the same fix for ruby container and ruby base container shown in bug 1641139. But even if it's properly shown, its position is not reasonable. This may need more investigation, as it's handled specially.
