Material-ui: [Theme] objects bouncing on input change

[dusanbass]

I have the next issue, and I'm not even certain that it is an bug or whatever, I need support and understanding :)

Imagine you have one input filed of the select type, something like
<TextField id="standard-select-currency-native" select ...
Then imagine you are watching the theme object passed from the MuiThemeProvider. If you inspect the previously mentioned TextField inside the ReactDevTools, you will see that the theme object is kinda _bouncing_.
What I mean by saying _bouncing_ is that you will see that all nested objects are appearing and disappearing (you must expand them, for instance see the onBlur inside the red square that I have provided in appended image).

So if you can, please explain is this normal, and why. Will it influence more unnecessary re-rendering and should I worry about it? Can I cure that issue?

Could you add minimal example please? Preferable in a https://codesandbox.io.

I have tried but without success. If you follow this link -> https://material-ui.com/demos/text-fields/#textfield and you will change the selected item inside this component:

But, here is my concern if you inspect for instance any other nearby component that is near it like this one

And inspect its provided theme

and look at the theme object, and expand the properties of that theme object (mixins and palette)

And continue watching them, when you change the value of the nearby component previously mentioned (the one with the currency select), you will see that whole theme object is bouncing. And I'm wondering why is the Theme object changing or bouncing?

Is it because of the state change of the container component?

@dusanbass The theme object is immutable. I would look into the React dev tool.

The theme object is immutable.

We don't seal or freeze it though. It's possible to mutate it. The components won't update though.

Thank you for the clarifications and suggestions guys! :)
