Double clicking on submodules from a project does not open a new tab but triggers a "submodule update" (the top bar appears but the tab with the submodule does not open).  
  
The "progress" bar on top shows this as command:  
  
`git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks submodule update --init path/to/submodule
Completato con successo.`  

  
Step to reproduce:  
• open a git progect using submodules (in my case nested)  
• open the main module into the tab  
• double click from the submodule menu on the left the desired submodule  
• see that the update triggers but the tab with the submodule does not open
