Nit - involed => involved

Nit - maybe name the variable nextWordMode or whitespaceMode instead of iosMode? (Or perhaps more verbose — nextWordModeInIOS).

> Source/WebCore/editing/VisibleUnits.h:45
> +WEBCORE_EXPORT VisiblePosition nextWordPosition(const VisiblePosition &, NextWordModeInIOS = NextWordModeInIOS::LegacyStopBeforeWord);

Nit - might consider removing the extra space before the ampersand in `const VisiblePosition &`, while we’re touching this line.

I usually use `enum class NextWordDirection : bool { ~ }` for these, but it doesn’t really matter since NextWordDirection isn’t stored anywhere.

> +    enum class NextWordModeInIOS { LegacyStopBeforeWord, StopAfterWord };

(Ditto with the bool enum class)

Thanks for the review.

Fixed.

Will use nextWordModeInIOS. whitespaceMode isn't right because we consider delimiters such as "," as well.

Sure, done.

Thanks for catching that. I always forget to specify the enum class' width. I've been coding too long in old C/C++ :(

Fixed this one too.
