NERDTreeToggleVCS not working as expected

[mversic]

I position myself in the project directory (directory containing .git) through the shell and then open some file inside project directory.

1. enter :NERDTreeToggleVCS and get NERDTree file explorer with all directories collapsed.
2. navigate with <j,k> and expand some of the directories
3. enter :NERDTreeToggleVCS to close NERDTree file explorer
4. enter :NERDTreeToggleVCS to open NERDTree file explorer again

What happens in the step 4. is that all directories are collapsed again as if I entered NERDTreeVCS

Documentation states that NERDTreeToggleVCS behaves as NERDTreeToggle and therefore In the step 4. I would expect that all expanded directories bellow the project directory are preserved and only directories above project directory get collapsed
