Underscore in interactive windows reported as "not defined"

[hmijail]

Environment data

• Language Server version: v2023.8.30 (in Pylance extension)
• OS and version: macOS Ventura 13.5
• Python version (& distribution if applicable, e.g. Anaconda): python 3.11.4 (brew)

Code Snippet

This happens both in interactive windows and notebook windows, and with all of "_", "__", "_1", etc.

Expected behavior

"_" and friends work as expected in interactive windows, so Pylance shouldn't complain that they are not defined.
