Incorrect syntax colouring in `for` loops

Environment data

VSCode - Version: 1.46.0-insider MS Python Extension - v2020.5.78807 macOS 10.14.6 Mojave Python 3.9.0 Virtual Environment - N/A It first showed up in github.com/craffel/pretty-midi python.jediEnabled: false python.languageServer - not set - defaults to 'Microsoft" python.languageServer setting: not set

Have not been able to explicitly set the Python Language Server - is this the problem?

Expected behaviour

Note the syntax colouring of for imstrument in.

Actual behaviour

Note the syntax colouring of for instrument in.

Note, that I changed the theme between the two images; I was trying to determine if the problem was todo with the theme itself - apparently not!

Steps to reproduce:

Construct a for loop where the for variable contains the letters `in within the name.

[EDIT] Construct a for` loop where the variable contains any reserved word within the name…

[EDIT] Not all reserved words cause this problem.

@carlca, syntax highlighting for Python is actually configured in VS Code rather than the Python extension (also true for many other languages). So this will need to be handled upstream.

@nullie, yes, please open a new issue in VS Code. Feel free to link to this issue there (or to that issue here).
