Add the following class stub somewhere in a project

class A
{
public:
    void foo();
    void bar();
};

Then click on "foo()" and trigger the refactoring "Add Definition Outside Class". This generates a function body.

Then click on "bar()" and trigger the same refactoring.

The result is

void A::foo() {}
// QTC_TEMP
void A::bar()
{
    
}

Expected: No "// QTC_TEMP" should be added to the code.
