expanding parents doesn't work on the left

[adamfk]

StateMachine parent state is not resizing to fit its children on save or on exit.

StateSmith Runner - Compiling file: `MySm.drawio.svg` (no state machine name specified).
Child outside of parent grouping (to the left).

        id: 13
        label: `OFF
               enter / set_leds(0);`
        parent.id: 2 (parent follows below)

        parent.id: null


You can enable exception detail dumping by setting `RunnerSettings.dumpErrorsToFile` to true.
StateSmith Runner - Finished with failure.

Might have something to do with children being to the left of the parent's origin line? Related to coords going negative?
