In my appBar component, I have three buttons that appear fine on large screens. However, when the screen size reaches 400px, they start stretching out of the appBar.
Here is how they look on large screens: https://i.sstatic.net/l3nJM.png

I attempted to remove margins and paddings but it did not solve the issue.
Furthermore, there are no elements causing additional margins. What could be causing this problem?
I created a sandbox to demonstrate the issue: https://codesandbox.io/s/spring-tdd-c1ocm?file=/src/App.js
