Ah, sorry, I hadn’t updated to the new version yet, so I hadn’t seen this addition to the theme yet.
Your solution works, but will likely be overwritten when you update the theme to any upcoming versions.
It seems you can also hide these elements in the theme configuration, which I would recommend, as that should not be overwritten with updates.
If you go to Appereance -> Customize, and then to Basic Settings > Default Content Setting and check “Hide default content from theme” that should do the trick.
