If you try to read context inside content prop of Meta component provided by start, the context will not be available, which is not expected as it's used directly under the provider.
<Ctx.Provider value={{ text: 'you should see this' }}>
<Html lang="en">
<Head>
<Meta
name="description"
content={useContext(Ctx).text} // ctx read here is not available
/>
</Head>
<Body>...</Body>
</Html>
</Ctx.Provider>

I'm interested in working on a fix if this is something that's considered a bug.
