How often does it reproduce? Is there a required condition?

It appears to reproduce every time when none of the target IPs are reachable, but only in the REPL. (It's possible that it also happens without the REPL, but I haven't seen it anywhere else yet.)

What is the expected behavior?

No ERR_INTERNAL_ASSERTION.

What do you see instead?

ERR_INTERNAL_ASSERTION.

Additional information

The DNS setup within the network appears to be rather complicated, and the error message fetch failed is expected when the network node cannot be reached via any of the associated A or AAAA records. However, the ERR_INTERNAL_ASSERTION error is unexpected.

I'm closing this as a duplicate of #46669 even though the reproduction in this issue is simpler. (cc @ShogunPanda)
