List _do shows syntax error for Object types

**UE4 Version**
4.23.1

**SkookumScript Version**
4.23.1

**Describe the bug**
When using `_do` on a `List` where the item type derives from `Object`, the IDE shows a red syntax squiggle for methods that don't derive from the `Object` base class:

The code compiles fine, but if highlighted shows the error:
>`The method 'actor_location()' does not exist for an instance of the class 'Object'`
