Wrong interpretation of MAX_VISIBLE_LIBRARY_HIERARCHY

For the statemachine: unit_test_state_machines/deep_libraries/library_middle2

It has 33 States (library state instances count as two states, one for the library wrapper and one for the state_copy).

If MAX_VISIBLE_LIBRARY_HIERARCHY is set to 3 than all 33 Models for the states are loaded, which is correct. 3 levels of hierarchies are shown if a show-flag is enabled, which is also correct.

If MAX_VISIBLE_LIBRARY_HIERARCHY is set to 2 also all 33 Models for the states are loaded as well, which is wrong! Only 2 levels of hierarchies are shown if a show-flag is enabled, which is actually correct. Thus, a lot of models are created, but not shown using the show flag.

For bigger state machines, this drastically increases the loading time by a factor of FOUR!
E.g. for the unit_test_state_machines/deep_libraries/sm with deepest libraries!

For our LRU state machines, this is even worse!
