Following up on https://github.com/reactjs/reactjs.org/pull/4486#discussion_r834319756 (/cc @acdlite )

React version: 18.0.0-rc.3-next-1159ff619-20220324

## Steps To Reproduce

1. schedule an update (e.g. `setState`) from within `useInsertionEffect` 


Link to code example: https://codesandbox.io/s/naughty-bogdan-boghf6?file=/src/index.js


## The current behavior

Update is applied and no warning is issued.

## The expected behavior

According to https://github.com/reactjs/reactjs.org/pull/4486/files#diff-a1c8ec10dc40c86b4bbd55ad3f0126835bd45e9aa9e56c846a2e28ad6dd6acffR602 `useInsertionEffect` cannot schedule updates. But `setState` seems to "work". Maybe this is just incidental because it's the first render?

I got the impression that this should definitely cause a warning (not implemented) but I wonder if we also should consistently drop updates from `useInsertionEffect`?

  }
   We disable time-slicing in some cases: if the work has been CPU-bound
   for too long ("expired" work, to prevent starvation), or we're in
   sync-updates-by-default mode.
   TODO: We only check `didTimeout` defensively, to account for a Scheduler
   bug we're still investigating. Once the bug in Scheduler is fixed,
   we can remove this, since we track expiration ourselves.
  const shouldTimeSlice =
    !includesBlockingLane(root, lanes) &&
    !includesExpiredLane(root, lanes) &&

    ? renderRootConcurrent(root, lanes)
