Summary [css-cascade] Hover specified only for an implicit scope does not work correctly

Created attachment 470397 [details] Saved HTML of the CodePen test case Steps to reproduce: 1. Open this test-case in Safari TP with the CSS Scoping flag on: https://codepen.io/kizu/pen/ZEZBLpK (or create an element with an implicit scope that contains `:hover` pseudo-class) 2. Hover over the first button. 3. Click on this button. In Chrome's implementation of CSS scopes the hover works correctly, but in Safari it does not trigger on hover, but is triggered when clicking on the button — probably repaint does not happen when necessary. This only happens when the `:hover` is applied _only_ as a part of the implicit scope, adding any other `:hover` for this button outside of it (regardless if it will be scoped) fixes the issue, so probably the `:hover` specified inside implicit scopes does not make the element subscribe to the state change?
