Steps to reproduce the problem:
1. install Vimium chrome extension.
2. Load any page.
3. Open console in dev tools. 
4. Find the 'vomnibar.html' frame is selected in the Execution Context Selector.

What is the expected behavior?
I expect the top frame to be selected as it usually is when the Vimium extension is not in use.

What went wrong?
It slows down development if I want to make use of the Vimium extension and use the console, because I must manually select the 'top' frame in the Execution Context Selector.

Other cases:

What steps will reproduce the problem?
(1) Open a site with a iFrame that runs JS, open DevTools without loading Elements Panel
(2) Add breakpoint in the iFrame's JS and pause there
(3) Observe that the console context selector switches to iFrame context on pause
(4) Evaluate any node in console (e.g. `document.body`)

Expected: Console context should stay on iFrame context
Actual: Console context switches to 'top'

Another symptom with the same cause:
- Open newtab page
- Right click, inspect an element
- Set a breakpoint in the iFrame
- Refresh to pause on the breakpoint

Expected: context selector should be the iframe
Actual: context selector switches to 'top'
