Environment:
  Google Chrome 24.0.1298.0 canary

Steps to reproduce
0. Enable "Show Shadow DOM" in "General" tab of DevTools setting
1. Open data:text/html,<input type=time>
2. "Inspect Element" on the time field
3. In the Elements panel, expand all of shadow nodes of the time field.  You'll see two or three <span>s with some aria attributes.
4. Make sure selecting the time field in the Elements panel
5. Open JavaScript console
6. Type   $0.value = "23:59";
7. Observe the shadow nodes

Expected:
 Shadow nodes in the Elements panel are replaced for the value "23:59"

Actual:
 Shadow nodes for "23:59" are appended in the Elements panel.  See attached screenshot.

input[type=time] with this structure is available only on desktop Chromium for now. We had better test with an element which is available on any platforms. e.g.  Prepare <input type=text>, then change the type like input.type = "checkbox"

OK. I'll change the test case soon.

It turned out that this issue does not happen when we change the type.
Hmm...

[Shinya Kawanaka]

Is it OK if I don't use <input />? This issue happens even if we don't use <input />.
I'll just use #shadow-root and appendChild/removeChild.

This sounds even better. It clarifies what the problem is.

Do you want to capture both states? I.e. that the addition was reflected in the inspector as well?
