Nice! r=mews

> Source/WTF/ChangeLog:9
> +        Add an internal flag to guard text selectin flipping while

Nit - selectin => selection

> Source/WebKit/ChangeLog:11
> +        This is currently guarded behind and off-by-default flag so that we can

Nit - "behind and" => "behind an"

> +static std::optional<SimpleRange> rangeForPointInRootViewCoordinates(Frame& frame, const IntPoint& pointInRootViewCoordinates, bool baseIsStart, bool selectionFlippingEnabled, bool &selectionFlipped)

Nit - instead of an out-reference (`bool& selectionFlipped`), I think we generally prefer to coalesce that into the return value in modern code (i.e. make this helper function either return `std::pair<SimpleRange, bool>`, or `std::pair<SimpleRange, SelectionWasFlipped>` where `SelectionWasFlipped` is a strongly typed enum)

This would also allow you to do something like `std::tie(range, selectionFlipped) = rangeForPointInRootViewCoordinates(frame, point, baseIsStart, selectionFlippingEnabled());` at the call site.

As long as we are nitpicking on "selection" spelling, here is another typo :-)

Nit - you can omit the `WebKit::` here.
