Steps to reproduce the problem:
1. visit http://output.jsbin.com/giwohoruka
2. right-click on the select element, chose "Inspect"
3. go to the Inspector, unfold the select node, and click on the option node corresponding to value "a"

What is the expected behavior?
At step 1: in the Inspector, the select node should be unfolder, and the option node you right-clicked on should be selected

At step 3: when selecting the option in the Inspector, the corresponding node, if it is the one currently selected and hence visible in the select, should be highlighted

What went wrong?
At step 1: the select node is selected in the inspector rather than the selected option node. Also, the select node is collapsed in the Inspector

At step 2: nothing at all is highlighted on the page, while a visible element (namely the option node) is selected in the inspector
