  [Cleanup] Only grid items may be out-of-flow-positioned and still participate in their FC layout
https://bugs.webkit.org/show_bug.cgi?id=285187

Reviewed by Antti Koivisto.

Only grid and flex use override containing block for their items, but only grid items
can participate in their FC layout when out-of-flow positioned.
