Paid Content Block - Guest View displayed to logged-in users and Log In button not functional when More Block is nested.

### Impacted plugin

Jetpack

### Quick summary

When a More block is nested in a Paid Content Block, a user who is logged in and visiting a post with a Paid Content Block will see the guest content. The Log In button is not functional (there is not even a link target associated with the button), and the Subscribe button is missing.

Expected behavior is that the subscriber content should be shown when a logged-in user visits the page, and there should not be any non-functional links.

### Steps to reproduce

- I started a Free site with the same theme (Quadrat), and I chose a premium style.
- I connected a Stripe account, and I made a Newletter tier subscription
- I set the site privacy to Public.
- I created a post with a Paid Content block, and I connected the Newsletter Tier subscriptions (monthly and annual) to that block.
- I added test content, including a More Block to the Subscriber view

Reproduce the issue in Jetpack with a Paid Content Block containing a nested More block, using a logged-in user and the Newsletter Tier subscription setup described. Trace why the subscriber view is not selected and why the Log In and Subscribe controls are missing or non-functional; done means logged-in users see subscriber content and all displayed links work.
