Element prototype oddity in Chrome console

Object.getPrototypeOf(document.createElementNS('html', 'div'))

1. When I run this from a script on Chrome 48 (stable) or 50 (canary) I get the expected/desired HTMLDivElement (codepen)
2. When I run this within the console on Chrome 48 I get Element (no HTMLDivElement or HTMLElement)
3. When I run this within the console on Chrome 50 I get Node (no HTMLDivElement, HTMLElement, or Element)
