What problem does this address?

Synced patterns with overrides are increasingly powerful and ideal for templated parts of the site.

One technique I increasingly use is having a standard set of blocks for a page banner that includes the Post Title block. In those cases, I hide the editor's Title field, so that the title is only editable through the Post Title block.

This does not work with Synced Patterns where the title is correctly displayed but is not editable. This means I still have to display the redundant post title field that's hidden on the front end, reducing the WYSIWYG-ness of the editor.

What is your proposed solution?

It seems that the Post Title block should always have editable text when in a Synced Pattern since the content is not stored in the block markup/meta data. If doing this, I'd consider whether the Featured Image block could similarly be editable in this context.

This would be a nice tweak in support of #59272, since it's a very "theme-like" usage of a pattern.
