Description Doug Russell 2015-02-20 19:03:12 PST

editingIgnoresContent() expects a non null parent node in order to behave correctly and previousLinePosition & nextLinePosition aren't performing that check. This manifests regularly when navigating via cursor with accessibility enabled. (Not an accessibility bug, just happens to encounter it.)
