m.top.getParent() has different behavior from Roku native brightscript

[adheus]

When running the following code in a not scope:

SomeNode.brs

sub init()
    m.top.myNodeField = CreateObject("roSGNode", "Group")
    ?m.top.myNodeField
    ?m.top.myNodeField.getParent() ' Should return m.top
end sub

On Roku brightscript implementation, getParent() returns SomeNode instance.

On brs, getParent() returns invalid.
