Description

When an accordion appears within a section / content only mode, it displays in a very noisy way in the sidebar with all its component blocks appearing. This makes the sidebar quite hard to work with, and it fill up a lot of the available space as flagged by @talldan in #72052 (comment)

One idea:

I think it might an idea to try adding the List View block support for Accordion and seeing if that provides a better experience.

This could be a better approach as it would mean only the root Accordion would appear in the sidebar, and its contents could be rearranged from the List View tab instead.

Step-by-step reproduction instructions

1. Insert a pattern into a post, page, or template
2. Click to edit the section
3. Add an accordion with a few items, and put some paragraphs in them
4. Click to exit editing the section
5. With the parent section/pattern selected see how noisy the sidebar looks
