Incorrect side-effect computation

We use custom state manager with modifiers proxy:
```js
function setShowPreloader(data, payload) {
data.view.showPreloader = payload
}

function setImageSrc(data, payload) {
data.src = payload
}

const bindState = (state, modifiers) => {
const res = {}
for (const key of Object.keys(modifiers))
{
res[key] = payload => modifiers[key](state, payload)
}
return res
}

const state = {
view: {
showPreloader: true,
},
src: '',
}
const controller = bindState(state, {
setShowPreloader,
setImageSrc,
})
controller.setShowPreloader(false)
controller.setImageSrc('http://localhost/image.png')
console.log(state.view.showPreloader, state.src) // expected: false 'http://localhost/image.png'
// received: false ''
```

after compilation setImageSrc will be removed (but setShowPreloader not).
