Why does scrolling appear in responsive developer mode in chrome?

Question

css

Hello.
Tell me,
why does the scroll appear in the adaptive developer mode in chrome?
If you just reduce the browser screen, then there is no scroll, there is no scroll in mozilla (there is no scroll in the adaptive developer mode either), the scroll appears only in the adaptive developer mode in chrome, this means that it will also appear on mobile ..?

Test on your phone and tablet, then you will know for sure if there is scrolling. You can fix it by deleting large blocks one by one - so you will know which one is "guilty".
