Current behavior 😯

Expected behavior 🤔

• The initial response should include the HTML for the modal
• The page should look the same as when JavaScript is enabled

Steps to reproduce 🕹

Steps:

1. Disable javascript in your browser
2. Visit https://mvjvg1.csb.app/
3. observe the blank page

I see a test for this was added as part of #16850

My apologies, I think this was all user error and assumptions/misunderstanding.

Closing this as I can now SSR the modal locally. Also, after looking at the other CodeSandbox examples, I believe they're just not set up for SSR but the example does work if the other SSR steps are followed.
