  Replace incorrect ASSERTs in RenderBox::containingBlockLogicalWidthForPositioned/containingBlockLogicalHeightForPositioned
https://bugs.webkit.org/show_bug.cgi?id=268714

Reviewed by Antti Koivisto.

ASSERT(containingBlock.isInFlowPositioned()) is stale now that backdrop-filter can make an inline box form containing block for out-of-flow boxes.
Instead let's just check that the incoming RenderBoxModelObject renderer can actually be a containing block for out-of-flow descendants.
