I talked to Erik about this issue and back porting the PRs merged for the original issue will not resolve this issue.
Fixed in master.20180525014609_98ef65d.
In an example dialog I whipped up, it appears that when I change the first drop-down, the second responds properly, but I'm unable to import the datastore and dialog that was provided in the original BZ. Do we know if the customer has a valid 5.8 dialog they can reproduce this issue with that I can test with to ensure I didn't oversimplify my dialog?

I've attached datastore and dialog export files for 5.8. I was able to get the dynamic "network" dropdown's auto-refresh working on 18.104.22.168 and 22.214.171.124 if I have both of these options selected:
tenant: Auto Refresh other fields when modified
network: Auto refresh
