# STEPS TO REPRODUCE: 1. inspect any page 2. add a CSS property to any rule on the page 3. close Web Inspector 4. reopen Web Inspector => the CSS property added in 2 cannot be found, but the style is still in effect (e.g. `color: red;` still changes the page's text color, even though it's not visible in the Styles sidebar)

Hm, I suppose I can use localStorage to handle this case.
