Description

In the featured image block, there is a setting called "resolution" (internal name "sizeslug"), with can be set to "Thumbnail", "Medium", "Large" or "Full size". This setting is only visible if a featured image is assigned. Further, is the image is to small, some of the options or the complete setting is not visible.
This makes sense for editing a blog post, but not for editing a template, since the images shown in template editing are just examples.

Step-by-step reproduction instructions

1. Install Wordpress 6.6.2
2. Create a new blog post and assign a featured image
3. Open the "Index" template in the site editor
4. Select a featured image block

Depending on which column you select, the "resolution" setting is visible or not. It should always be visible.
