This problem is observable only from WebKit API, and not visible from DOM.
The test case uses textInputController.firstRectForCharacterRange() to reveal it.

The expectation for LayoutTest/editing/selection/move-left-right.html is also suffered by this problem,
although its difference is minor issue for that  test case.

A problem observable via textInputController.firstRectForCharacterRange() would probably affect inline text input, too.
