Wrong login suggested when two hosts share a parent domain (a.foo.com vs. b.foo.com)?

1Password's inline suggestion matches logins by registrable domain rather than by full hostname. On proxmox.anderswallgren.com:8006 it suggests my "ntopng.anderswallgren.com" login, even though the "proxmox - root" item has that exact URL in its website field and appears first in both the extension list and the field dropdown. Different hosts under one domain (a.foo.com vs. b.foo.com) are separate apps with separate credentials, so the suggestion should prefer an exact hostname match before falling back to the parent domain.
Does anyone else see this? It basically renders the new auto-fill useless to me.
