Rendered large document without any Suspense boundaries error

[JamesSingleton]

I noticed that some of my articles that get decent in length result in the following error in Vercel's logs

[Error: This rendered a large document (>512 kB) without any Suspense boundaries around most of it. That can delay initial paint longer than necessary. To improve load performance, add a <Suspense> or <SuspenseList> around the content you expect to be below the header or below the fold. In the meantime, the content will deopt to paint arbitrary incomplete pieces of HTML.]

I wasn't getting this until I migrated my existing app over to the turbo-start-sanity structure. I am wondering if this is a result of ppr being enabled or if y'all have seen this before or not.
