Issue with grapjs.init()

Apparently options passed to grapjs.init() are not being deep cloned and same object is being mutated which was originally passed. This is creating a weird issue, I cannot do this

this._builder = grapesjs.init({
            container : '#gjs',
            plugins: ['gjs-preset-newsletter'],
            pluginsOpts: myOptions
});

Mutation can be seen by logging myOptions before init and the result is very weird, editor without any components

I had to fix it using cloneDeep of lodash like

this._builder = grapesjs.init({
            container : '#gjs',
            plugins: ['gjs-preset-newsletter'],
            pluginsOpts: cloneDeep(myOptions)
});

My version is "grapesjs": "^0.14.43",
