Terminal clears on typing period (.) following `pip install <package>==<num>`

Describe the bug

Noticed a strange bug when using the terminal in a notebook. I activated my virtual environment and started to install a specific version of a python package: pip install package==1.1.11.

As soon as I type the first decimal point in the version number, the terminal clears and looks like this:

I can't reproduce this by simply typing 1., ==1. or even install <package>==1.. Only pip install <package>==<number>..

Additionally, I can't reproduce this when I don't activate my venv, and I don't encounter this behavior at all in my native terminal.
