Re: [csswg-drafts] [css-writing-modes] Question about implementability of the "different writing-mode value than its containing block" section of the spec

Given that a mismatched writing mode on an inline box results in it becoming a block container, we can assume that checking writing-mode on the parent of an inline is equivalent to checking writing-mode on its containing block. So we can update the spec to check the parent box, and that solves that problem.

Wrt the conflict with the blockification rules, the intent of this rule is that it only affects the internal display type, i.e. if it is `flow` it becomes `flow-root`, and is otherwise unchanged. The outer display type is handled by blockification rules; they don't affect the inner display type. (CSS2.1 mixes both, but L3 separates these concepts.)
