Current Behavior

the following code is working in one-time script, but fail in widgets

    lvgl.clear();

    local box = lvgl.box({x=100, y=10})
    box:rectangle({x=0, y=0, w=100, h=100, color=YELLOW, filled=false, rounded=8, thickness=4})
    box:rectangle({x=10, y=10, w=100, h=100, color=YELLOW, filled=false, rounded=8, thickness=4})

Expected Behavior

I expect the we can use OO style on widgets as weel

box:rectangle()

Steps To Reproduce

    local wgt={zone=zone, options=options}
    return wgt

    wgt.options=options
    lvgl.clear();
    local box = lvgl.box({x=100, y=100})
    box:rectangle({x=0, y=0, w=100, h=100, color=ORANGE, filled=false, rounded=8, thickness=4})
