Jupyter notebooks are opened instead of showing diff

[stefano-xy]

I'm using gitHistory 0.6.14 and vscode 1.52.1, with python/jupyter support installed. I have some Jupyter notebooks (.ipynb files) under version control. When trying to show the diff of one of them against the previous version or theworkspace, the diff window shows up for a short moment then it's replaced by the opened notebook file. It's impossible to examine the diff because this is replaced by the file content itself.

The notebook file should not be shown (and relative ipython interpreter should not be started) when just trying to show the diff.
