Describe the bug
A clear and concise description of what the bug is.

When triggering hmr with prefresh while using suspense & lazy the following error gets thrown:
(Note that you have to trigger the HMR from a different file that you main entry file)

suspense.js:235 Uncaught (in promise) TypeError: t.__e is not a function
    at U (suspense.js:235)
    at L.__c (suspense.js:124)
    at Object.n.__e (suspense.js:18)
    at I (index.js:255)
    at m (children.js:137)
    at I (index.js:198)
    at m (children.js:137)
    at I (index.js:198)
    at m (children.js:137)
    at I (index.js:198)

From what I can gather on suspense.js#L18 we check if the vnode is suspended, but and the check on suspense.jsL235# expects the parents _suspended property to be a function or false, but somewhere this _suspended property got rewritten to true. (How is this even possible?)

To Reproduce

The repro is more complicated since it involves prefresh but I'll try to create a minimal example tomorrow!

Steps to reproduce the behavior:

1. Create an async function that returns an element
2. Add a suspense + lazy that uses the async function
3. Import the suspense + lazy component in a separate file and render the app from that file
4. Cause a hmr refresh from the first file and see the error

Expected behavior
What should have happened when following the steps above?
No error
