Should this comment be ASCII only?

We could have a helper function that converted ScrollingDirection + CGSize to the right output. Then it could be used in WKKeyboardScrollingAnimator.mm 'distanceForIncrement', too.

But not today.

Should this assert !horizontal?

No, the only thing that has a problem with this is the review tool. We have this problem a lot with smart quotes too :)

No, definitely not. The default left/right arrow key behavior is "by line" and uses the vertical line height.
