Fix bad JS rendering in "Allow Desktop Notifications" workflow

Summary:
See downstream <https://phabricator.kde.org/T5404>. This code was doing some `.firstChild` shenanigans which didn't survive some UI refactoring.

This whole UI is a little iffy but just unbreak it for now.

Test Plan: Allowed and rejected desktop notifications, got largely reasonable UI rendering.
