David Shin c7ccd24b1c Bug 1974230: Add UA-only pseudo-selector for suppressing frame generation of elements during printing. r=firefox-style-system-reviewers,emilio ... The plan is to apply this internal pseudo-selector during construction of print selection subtree - Currently, every node outside of the selection is deleted, but elements outside of the selection would have this pseudo-selector applied instead. In the UA stylesheet, we ensure that elements matching this pseudo-class have `display: none` applied. This change would make print selection behave more consistently by preserving matching for tree-structural pseudo-classes; however, the main reason for this change is to allow the copied document for print selection can preserve the relation between every `<style>` node and `Stylesheet`, which is required for `@scope` with implicit scope to behave properly (As the implicit scope root is defined as the parent of the style node). Without this change, attempting to preserve relations between `<style>` and `Stylesheet` would result in having all stylesheets deleted because `<style>` nodes are never selected, and thus deleted, then causing the deletion of the stylesheet.
