Prerequisites
Stencil Version
3.2.2
Current Behavior
This is a extension from the Stencil Discord thread, where a issue was asked to log an issue that can replicate the issues my team is seeing while trying to use NextJS 13.4+ with Stencil 3.3.2 and hydrate renderToString with a custom server to provide the server with a hydrated document.
Example screenshot

Expected Behavior
I expect the server and client to be in sync from an initial render, with the expectation that fetching and interactive elements won't be available
