Unfortunately this is dependent on VS Code itself. In order to make a change it will require a change upstream. If you would like to see such a change then please open an issue at https://github.com/microsoft/vscode.

This comes from MagicPython

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.81.1. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

I've opened MagicStack/MagicPython#259 on the upstream repo for this.

I know this is closed but check this out: MagicStack/MagicPython#114 (comment)

r"" is fore RE, use R"" for raw string

Thank you, I didn't even know about this until you told me.
But this is not grammar for python and is not part of pep.
As a specially provided feature, at least it should be turned off by default ,or use R for RE.

I've noticed a lot of debate on the MagicPython side as well, and dissatisfied with status quo.

Yeah pretty annoying to me as well, and most of the themes follow this rule.
