Fix handling for isEditable and isSelectable states

This patch fixes how isEditable and isSelectable properties interact, ensuring
proper behavior when either property changes state. The implementation now
correctly sets interaction modes based on both properties, adding support for
the non-interactive state when neither selection nor editing is enabled.

fixes #81
