Footnotes in sync patterns can't be edited

[druxstr]

Description

Expected

Footnotes content should be editable.

Happening

When a Footnotes block is added to a Sync Pattern, footnotes can't be edited anymore.

The footnotes can't be edited from the Post/Page content, as the Sync Pattern is stored in the content as :

<!-- wp:block {"ref":id} /-->

When editing the Sync Pattern itself (using "Edit original"), a message says that Footnotes are not supported :

Footnotes are not supported here. Add this block to post or page content.

Result : Users can edit the footnote content neither from the Post content, nor from the Pattern editor.

This issue occurred on a blank new WordPress with no plugin.

Step-by-step reproduction instructions

From the editor :

1. Add a footnote to some content using the Footnotes block
2. Add a Group
3. Move the Footnotes block in the Group
4. Turn the Group into a Sync Pattern (Group > Options > Create pattern)
5. Try to edit the footnote

You now can't edit the footnote content from the Visual or Code editor.

@druxstr That's an interesting one as footnotes doesn't work like other blocks (it can't be inserted in the same way) and probably for this reason.

Thanks for flagging it though, it's something to think about.
