It seems that the decision to diverge from the vim behavior was made here. Is there any context available? Can we maybe have a setting which controls this?

@sygi It was so long ago so I cannot say for sure. Nowadays I only use neovim or vim, and the behaviour is if I'm in Insert mode and select some text with my mouse, it actually triggers the terminal selection mode instead of going to neovim/vim visual mode

It could be my setting that disables mouse somewhere as well, but then it also means that behavior similar to mouseSelectionGoesIntoVisualMode: false

Side note: I have terrible perfomance issue with VSCodeVim when using Jupyter notebook so I usually disable it ...

Hmm, the behavior you describe happens when you disable mouse handling by vim; you'll always be able to achieve that via ~/.vimrc.

I kinda like the vim mode in jupyter notebook, except for this issue ^^
I prepared a quick fix above.

I just want to say that, please double check with other maintainers about the intention and plan with that setting. Even if it may not affect me anymore, people may notice the changed behavior and ask about it (think about non-jupyter users). And we end up in a complaining loop.

Anyways, I do wish the vim support for notebook become better.

Of course, that's the point of this thread / issue :)
