SVG being downloaded client side in a 'server only' component NextJS#883

## 🐛 Bug Report In NextJS 13.4.1, SVGs rendered inside a server component are being downloaded client side, when a `use client` component is present. ``` 'server-only' component <div> <ClientSideComponent /> // using 'use client' directive <div> <Svg /> // using SVGR (download should happen server side) </div> </div> ``` The page that renders this server-only component, appears in the network tab with 208kbs because its downloading `<ClientSideComponent>` (which is client-side, so its okay) and `<Svg>` (which is a SVG, and this is not okay) If I comment `<ClientSideComponent>` and run `build && start`, the page is not downloaded client-side, not even the SVG. So, my conclusion is that, `<ClientSideComponent>` client component is triggering the SVG to render client side when its inside an server-only component... However, when I removed the SVGR library, and installed other SVG to React Component lib, this is not happening. Only the `<ClientSideComponent>` is being downloaded. ## To Reproduce Steps to reproduce the behavior: (Read README in repo to reproduce) ## Expected behavior When rendering a react server component server side, all its children should be also rendered server side, unless the children explicitly has `use client` directive. ## Link to repl or repo (highly encouraged) [Repo to reproduce](https://github.com/ricardo-fnd/rsc-test)
