bs4SidebarMenuItem condition is not respected when it has sub-items

[lanceupton]

Details of Issue

When a conditional bs4SidebarMenuItem contains one or more bs4SidebarMenuSubItems, the condition argument seems to be ignored and that tab remains visible always.

Here, "Tab A2" shouldn't be displayed:

Here, observe the "Tab A1" (with no sub-items) behaves correctly and only displays when the appropriate condition is met:
