managing nodes that are not groups

[Shlangman]

case:
there is “group 1”
inside this group there is a node “node 1” and there are “group 2” and “group 3”.
In the “Fast Group Muter” node we see “group 1”, “group 2”, “group 3”.

we turn off all the groups, we turn on “group 2”. In this case, “group 3” remains disabled, “group 1” is enabled (because it is a parent). but “node 1”, which is part of “group 1” and is not a group, is not enabled. thus, “group 1” seems to be enabled, but the nodes included in it that are not groups remain disabled.

It is necessary to make nodes that are not groups obey the same rules as the groups themselves: if their group is enabled, the nodes must be enabled as well. and vice versa.
