The more traditional thing would be to use operation[] here.

I don't think you need the braces at all here. It should default initialize the members by default.

> Source/WebCore/platform/text/WritingMode.h:131
> +constexpr std::initializer_list<BoxSide> allBoxSides = { BoxSide::Top, BoxSide::Right, BoxSide::Bottom, BoxSide::Left };

I think this would make more sense as std::array<BoxSide, 4>. Keeping initializer_list is mostly best used as a parameter to a function.

I also think we should try to replace this, perhaps as a follow up, with specific iterators on RectEdges.

like with the other use, I think this would be better as a std::array.
