Auto indentation of newlines fails when using subscript operator [] in function call (C/C++)

Example:

this->someMethod(argument0, argument1, argument2,
                 argument3, argument4); // Auto-indentation OK

{{this->someMethod(argument0, argument1[0], argument2, // [] used.
    argument3, argument4); // Auto-indentation broken.}}

This is very reproducible on all recent Qt Creator versions and, since I've been using Qt creator for about 15 years now, I know for sure that this bug is at least 5 years old, if not older.
