Description

It's been reported that the orientation settings are not showing consistently. For example using the skatepark theme and adding a row block in the post editor results in orientation settings now showing at all:

Skatepark does not have anything in theme.json to hide these settings.

Step-by-step reproduction instructions

1. Activate the skatepark theme
2. Open the site editor
3. Add a row block
4. Notice that the orientation settings are unavailable.
