It would also be nice to add a new layout test for this, as well.

Nits -
  vertial => vertical
  correclty => correctly

> Source/WebKit/WebProcess/WebPage/ios/WebPageIOS.mm:1501
> +    if (existingSelection.rootEditableElement()->computedStyle()->isVerticalWritingMode()) {

Wouldn't this only work when the selection is in editable content? I think this will also crash when trying to move selection handles in non-editable text on iOS :P

We probably want to check the RenderStyle of the container node of the base VisiblePosition instead.

Can we create a regression test?

auto node =

or

    WebCore::Node* node =

The selection test infrastructure is currently broken by changes in UIKit. There are plans to change how those tests are written, and I will add a test with those changes.
