Using dot '.' as member access operator fails to trigger auto completion/intellisense when used inside macro.

Bug Summary and Steps to Reproduce

Bug Summary:
There is a feature that allows to type '.' as access member operator on any type to show completion window with all members and then it resolves to '.' or '->' automatically.
This feature fails when used inside macro call.

Steps to reproduce:

1. Paste code (file.hpp):

#define myMacro(value) 

struct MyStruct
{
    int value;
};

struct Container
{
    int value2;
    MyStruct *myStruct;
};

void func(Container *container)
{
    myMacro(container.                         // <- problem here
}

2. Go to 'func' function and type in 'myMacro(container'
3. Now when we type access member operator '.' normally popup with suggestions should appear - but it doesn't.
4. Instead of '.' type '->' - suggestions appear.

Expected behavior:
After typing '.' in macro call we should see suggestions with struct members just like after typing '->'.
'Trigger Suggest' command (CTRL+SPACE) doesn't work on '.' but works after '->' when used in macro call.

Reproduzieren Sie das Problem in file.hpp mit VS Code 1.108.2 und der C/C++-Erweiterung 1.32.2, beginnend mit dem Makroaufruf in func und durch den Vergleich von '.' mit '->'. Verfolgen Sie das Vervollständigungsverhalten beim Memberzugriff innerhalb von Makroargumenten; abgeschlossen ist die Aufgabe, wenn '.' dieselben Membervorschläge wie '->' öffnet, auch wenn Trigger Suggest aufgerufen wird.
