[ANSI JOIN] array query hangs

The indexes present are:

default(VMs)

standard_bucket0(VMs)

This query:

select * from standard_bucket0 s INNER JOIN default d ON (d.VMs == s.VMs) LIMIT 10

Also hangs with the same datasets I gave you earlier in MB-27763, this may even be the same issue. Basically VMs is an array in the dataset that looks like so:

"VMs": [
{
"RAM": 10,
"os": "ubuntu",
"name": "vm_10",
"memory": 10
}]

Explain is attached here:
