Description
Hi there,
My VSCode does not work well on highlight syntax with python function annotation. Details are following:
-
Editor name and version: VSCode version 1.62.3
-
Platform: Windows 10
-
Color scheme: Any (primary using Tokyo Night theme)
-
MagicPython version: latest
-
A sreenshot:

-
5-10 lines of surrounding code:
def gcd(a: int, b: int) -> int:
if a == b:
return a
else:
if a > b:
return gcd(a-b, b)
else:
return gcd(a, b-a)
def gcd2(a: int, b: int):
if b == 0:
return a
else:
return gcd2(b, a % b)
Any ideas?
Thanks

Research direction
No implementation file or test is named. Reproduce the report in VS Code 1.62.3 on Windows with the supplied Python snippet, then trace the syntax-highlighting grammar used by MagicPython. Done means function annotations in the example receive the expected highlighting without regressing the surrounding function syntax.
