Steps to reproduce the problem:
1. Inspect a radio input
2.  Select one of them
3. Select another
4. Dev Tools does not mirror state of DOM
5. Set <input>.checked=true in console
6. Inspector does not update
7. Change "checked" attribute in inspector, input not checked (probably caused by "dirty checkedness" compliance with W3C standard, but still just terrible...more of a nice to have given the standard I suppose).

What is the expected behavior?
checked attribute should be added to element in inspector. Inspector should show valid information that doesn't deviate from <input>.checked in the console.

What went wrong?
Was trying to debug a css slideshow hack using checked inputs (original source here: http://www.cssscript.com/demo/basic-image-slideshow-with-pure-css/), and could not see which slide was being selected. This was maddening in debugging our implementation.

Did this work before? N/A 

Chrome version: 53.0.2785.143  Channel: n/a
OS Version: OS X 10.10.5
Flash Version: Shockwave Flash 23.0 r0

Even if we can't get changes in inspector to replicate back to the page, at the very least inspector should show the current state. Should not need to use the JS console to debug a JS-free slideshow implementation.
