What steps will reproduce the problem?
1. Open a website
2. Right-click on the site's background, select 'Inspect'


What is the expected result?
The dev tools open.


What happens instead of that?
The dev tools open, but the style that was applied to the website disappears. It's just like all the css files were suddenly not available.


Please provide any additional information below. Attach a screenshot if
possible.
I have not noticed a way to reproduce this bug repeatedly. I see it happen once in a while.
My settings have the dev tools open as a pane on the right of the window.
Upon resizing the dev tools pane, the style reappears.
