Modified scale resets after dragging/rotating model

[dariuslung]

Describe the bug I am trying to modify the scale of a model in realtime, so I resorted to obj.set({scale: [x, y, z]}) and it does work as long as I don't drag or rotate the model. Otherwise it gets reset to the original value.

To Reproduce Steps to reproduce the behavior:

1. Add a model to threebox
2. Manually override the scale with obj.set() or obj.scale.set()
3. Drag or rotate the model
4. Scale gets reset

Expected behavior Scale should stay as set?

Relevant Code

const step = 0.1;
window.addEventListener('keydown', function (event) {
    switch (event.key) {
        case '+':
        case '=':
            // PROBLEM Resets upon moving/rotating
            curScale.x += step;
            curScale.y += step;
            curScale.z += step;
            myModel.set({ scale: [curScale.x, curScale.y, curScale.z]});
            console.log(curScale);
            tb.map.repaint = true;
            break;
        case '-':
        case '_':
            curScale.x -= step;
            curScale.y -= step;
            curScale.z -= step;
            myModel.set({ scale: [curScale.x, curScale.y, curScale.z]});
            console.log(curScale);
            tb.map.repaint = true;
            break;
    }
});
