Variables view doesn't show dict key if it has double underscores

[parched]

Type: Bug

Behaviour

Expected vs. Actual

I expected all keys and values to be shown in the variables view, but keys that around surrounded by double underscores are only present under "special variables"

Steps to reproduce:

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.10.8
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Venv
• Value of the python.languageServer setting: Pylance

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

User Settings

Similar behaviour when using variablePresentation settings for protected variables

Settings added to launch configuration:
"variablePresentation": { "protected": "group" }

Does this actually belong in https://github.com/fabioz/PyDev.Debugger? Perhaps @fabioz might know?

[fabioz]

@karthiknadig this should be moved to debugpy.

[karthiknadig]

I will move it.
