What I did
This bug did not reveal itself until functionality was required on it, meaning it always was doing this but never mattered until now.
It is supposed to use the generic Node class, not GethDev, but they both come from the same provider and the order is not deterministic so sometimes it would be one or the other. However, the chain ID caching mechanism fails if it is does not use the Node class (as of #2464), so it became a bug at that point, thankfully not released yet.
fixes: #2449 (comment)
How I did it
adjust if statement to ensure right class
How to verify it
you can consistently use custom networks again
