[Pharo-project] Crashing the image with polymorph in one line :)

Hi gary I wanted to remove the class ComponentLikeMorph from the system. So I redefined ScrollPane to be a subclass of the superclass of ComponentLikeMorph MorphicModel subclass: #ScrollPane instanceVariableNames: 'scrollBar scroller retractableScrollBar scrollBarOnLeft getMenuSelector getMenuTitleSelector scrollBarHidden hasFocus hScrollBar' classVariableNames: '' poolDictionaries: '' category: 'Morphic-Windows' it works in pharo 64 but it crashes systematically the vm when polymorph is loaded.
