Description

When an implicit conversion member function is made to a type with a name longer than 4 characters, the rest of the class following the end of the function is grayed out.

Steps to Reproduce

1. Create a new file with C++ syntax highlighting
2. Place the following code in the file:

struct Hello {
  // Try getting rid of the asterisk, or making "world" one letter shorter.
  operator World*()
  {
    return convert_to_world(this);
  }

  this_should_be_blue this_should_be_red = but_everything_is_just_gray
};
