Just 2004-2020 is fine.

This check is not necessary.

I think this name is too short. I would not say that "a selection is horizontal". I think a good name could be "startsInHorizontalWritingMode".

> Source/WebKit/UIProcess/ios/WKContentViewInteraction.h:439
> +@property (nonatomic, readonly, getter=_isHorizontalWritingMode) BOOL _horizontalWritingMode;

Not thrilled with the naming here. Saying that "content view is horizontal writing mode" doesn’t make sense. Maybe "is in horizontal writing mode" would be better, but even that doesn’t seem quite right.

But I guess this is UIKit SPI, not something we are naming?

Cool

OK. I added as a fast path (without measuring) but it's cool to remove.

I like your suggestion! I'm renaming...

I'm adding the SPI. So, we can name it! I was having a hard time naming this thing throughout the patch....I'll go with isInHorizontalWritingMode for now.

After thinking about this some more, I decided to implement the -markedTextRange API instead fo adding this SPI. See bug #211148.
