Behaviour of WHMCS\Domains\DomainLookup\SearchResult::STATUS_UNKNOWN

[playmono]

Hi,

I'm developing some modules for WHMCS and I noticed some inconsistency behaviour using WHMCS\Domains\DomainLookup\SearchResult::STATUS_UNKNOWN.

When I Check Availability from Client Area (through CheckAvailability function), if I return STATUS_UNKNOWN, Client Area says that that domain is unavailable:

However, in suggested domains, when that domain shows up to be checked (consequently to call CheckAvailability function again), if I return STATUS_UNKNOWN, it allows me to add to the cart:

Conclusion: When I return STATUS_UNKNOWN for a domain, I can't register it through the regular way but I CAN register it through suggested domains.

I don't know if I'm missing something... Can someone clarify this?

Thank you.
