Expected behavior of get_available_prefixes of a container network

[Omripresent]

Hello,

I'm wondering what should be the expected behavior of the function get_available_prefixes() when operating on a container network.

Within the UI if a container network has no VRF assigned and a new subnet is created within said network with a VRF assigned it still shows under the Child prefixes tab.

That behavior does not seem to match the output of get_available_prefixes() where it matches vrf=None in the function's filter.

Is that expected to behave differently from the UI?
