The basedOn property of the object style has been read, but why isn't it actually working?

Hi @dublove here is a function to do the "Reset to Base".

/**
 * @file Reset Object Style.js

 * Equivalent of clicking the "Reset To Base" button

function main() {

    var doc = app.activeDocument;
    var myTestStyle = doc.objectStyles.itemByName('Test');

    // reset the style to its base style
    resetObjectStyle(myTestStyle);

};
app.doScript(main, ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT, 'Reset Object Style');

/**
 * Resets the object style to its base style.

 * @param {ObjectStyle} style - the style to reset.
 */
function resetObjectStyle(style) {

    var baseStyle = style.basedOn;

    if (!baseStyle.isValid)
        return alert('Object style cannot be reset due to missing base style.');

    style.properties = baseStyle.properties;
    style.contentEffectsEnablingSettings.properties = baseStyle.contentEffectsEnablingSettings.properties;
    style.objectEffectsEnablingSettings.properties = baseStyle.objectEffectsEnablingSettings.properties;

    style.basedOn = baseStyle;

};
