Research direction
No source file or test is named in the issue. Start by locating the Python grammar and token-scope rules responsible for :=, then compare the scopes produced for if m := x with the intended single walrus-operator token; done means the operator is highlighted consistently and its colon and equals signs are no longer separate tokens.

Description
From @BornForFever in https://github.com/microsoft/vscode/issues/94999
The walrus operator :=(an operator to allow you to make assignments in an expression, see PEP 572) is highlighted as 2 different colors. And I tried inspecting tokens and scopes, and found that : and = were treated as 2 tokens.
