For example, given the CSS code: ``` body { color: black; } @scope (.foo) { :scope { color: red; } :scope::after { content: ' more text'; } span { color: green; } } ``` and the HTML code: ``` <body> Some text </body> ``` When `foo` class is removed from ``, the text color in `` remains as red, instead of falling back to be the body color (black); "more text" remains instead of being removed. But the text color in `` is correctly falling back to its parent's color, which is red.
