Re: [csswg-drafts] [css-writing-modes-4] Allow sideways-x and vertical-x to share a block formatting context? (#10714)

FYI, my thought that this would be simple to do in Chromium turned out to be wrong.  The underlying problem is that coordinates of floats during layout are stored in logical coordinates, which [differ](https://www.w3.org/TR/css-writing-modes-4/#logical-to-physical) between `vertical-lr` and `sideways-lr`, which causes floats in a BFC that mixes those two writing modes to get swapped top/bottom.
