Nesting aliases does not work as advertised

[ErikvL]

I have several single host aliases (One name, One IP).
Then I have a nested alias that groups a few of those aliases.

Such a nested alias added to a rule works.

But, I also have a nested alias that groups a few of the single hosts aliases and the above mentioned nested alias.

Having this multilevel nested alias in a rule does not work for the nested alias in the group.

The nesting is as illustrated below. Similar to what is documented here: https://docs.opnsense.org/manual/aliases.html#nesting

alias A
  alias for IP 1
  alias for IP 2
  alias B
    alias for IP 3
    alias for IP 4
