  [content-visibility] it should trigger a layout if the value of content-visibility is changed from hidden to others
https://bugs.webkit.org/show_bug.cgi?id=248790

Reviewed by Rob Buis.

Per[1], content-visibility: hidden turns on contain:size. Contain:size would change the layout size of the element.
So when an element's content-visibility value changes from hidden to other, it should trigger a layout, vice versa.
