Bug Summary and Steps to Reproduce

Bug Summary:
Special cases where variables are highlighted in the color of the macro definition

Steps to reproduce:

1. Define two macro definitions, with macro definition 1 pointing to macro definition 2, and macro definition 2 pointing to an assignment statement, with macro definition 2 being longer than macro definition 1
2. Use macro definition 1 and macro definition 2 respectively
3. Macro Definition 1 has incorrect syntax highlighting in parentheses, but Macro Definition 2 is correct
4. Local variables within the brackets of macro definition 1 are partially highlighted in the color of the macro definition and depend on the length of macro definition 2

Expected behavior:
Variables are correctly highlighted

Hi @meijialun,

Thank you for the bug report. We saw this in Visual Studio too. A fix was made and we will get it in VS Code the next time we update the language server.
