Research direction

Start by reproducing the reported Python snippet in VS Code 1.81.1 using MagicPython and compare the highlighting with the expected and actual screenshots. The work is done when backslashes in the raw string are no longer highlighted as escape characters while ordinary escape sequences retain their highlighting.
