Chrome emits this notice when using VisualEditor anywhere.
'Range.detach' is now a no-op, as per DOM (http://dom.spec.whatwg.org/#dom-range-detach).
Looks like more than the typical deprecation, because it's been replaced with a no-op. No idea if we/Rangy are relying on it doing something. Could cause all kinds of weird state inconsistencies.
Version: unspecified
Severity: major
