Freeze screen in chrome debugger / DevTools panel for popover inspection?

Issue

I'm using the chrome inspector to try and analyze the z-index of a twitter bootstrap popover, and finding it extremely frustrating...

Is there a way to freeze the popover (while shown) so that I can assess and modify the associated CSS?

Placing a fixed 'hover' on the associated link does not cause the popover to appear.

Solution

Got it working. Here was my procedure:

1. Browse to the desired page
2. Open the dev console - F12 on Windows/Linux or option + ⌘ + J on macOS
3. Select the Sources tab in chrome inspector
4. In the web browser window, hover over the desired element to initiate the popover
5. Hit F8 on Windows/Linux (or fn + F8 on macOS) while the popover is showing. If you have clicked anywhere on the actual page F8 will do nothing. Your last click needs to be somewhere in the inspector, like the sources tab
6. Go to the Elements tab in inspector
7. Find your popover (it will be nested in the trigger element's HTML)
8. Have fun modifying the CSS
