This is a bug in our TextMate grammar (https://github.com/MagicStack/MagicPython). There's some discussion about possible approaches to fixing all of our issues of this type in https://github.com/microsoft/pylance-release/issues/5824. That issue also includes a list of isses that have been filed against MagicPython on escape sequences in raw strings, so it's a known pain point. We haven't decided how to address this class of issue yet.
