Selected rows where not highlighted when returning to the change-list
after clicking "No, take me back" on the deletion confirmation page.
This commit uses the CSS :has() pseudo-class to apply the highlight
without requiring the .selected class, which is added by JavaScript
on the click event.
Once all supported browsers have :has() available, the .selected
selector and the JavaScript to add the class can be removed.
