Switching to a branch on a nested repository opens a closed aliased top-level project #108

Bug description
I have an out of workspace "main" project that contains several nested repositories. This I understand is a semi-supported configuration (the nested repositories part), and it tends to mostly work, except for some functionality notably the Synchronize View family of comparisons. To cope with this limitation I also maintain top-level "helper" projects that directly contain the nested repositories. I only use these projects when I need to run a Synchronize View comparison, such as Compare With/Branch, and normally keep them closed to conserve memory and avoid duplicate files in the workspace. Unfortunately whenever I switch between branches using nested folders/repositories in the main project these top-level aliased projects get opened as a side effect which leads to confusion later due to the aforementioned duplicated files now being present in the workspace. I have to remember to close them whenever I switch to another branch. Hope this makes sense.
The following is an attempt to illustrate my workspace setup and repository associations. project_foo and project_bar are the "helper" projects that are normally kept closed. Switching branches in foo_repo via folder_foo would open project_foo if it was previously closed as an undesirable side effect.
project_main [bogus_local_main_repo]
folder_foo [foo_repo]
folder_bar [bar_repo]
project_foo [foo_repo]
project_bar [bar_repo]
Actual behavior
Aliased project is opened.
Expected behavior
Aliased project should stay closed if it's closed.
