Fixed sticky URL when using Escape to close view theme modal

no issue

- we were missing handling for the view-theme modal being closed outside of a route transition meaning the URL would stay on `/settings/design/view-theme/Theme` even though it's the index that was shown, preventing the same theme being viewable again and back/forward behaving as expected
