Why does the scrollbar appear even when the inner element is smaller in CSS transformation?

Question

Why does the scrollbar appear even when the inner element is smaller in CSS transformation?

Please check out this link

.wrapper { 
  width: 200px; height: 200px; padding: 10px;
  border: 1px solid #888; overflow: auto;
}
.scale { 
  width: 400px; height: 300px;
  background-color: red; 
  transform: scale(0.4);
  transform-origin: 0 0; transition: all 0.5s ease-in-out;
}
.scale:hover { 
  transform: scale(4); 
}

When the inner div is visually smaller than its wrapper due to transformation, one would expect the scrollbar not to be visible.

However, there is a difference in behavior between Chrome and IE. In IE11, both x- & y-scrollbars are visible, while in Chrome only the y-scrollbar appears.

The hover effect over the inner div functions correctly.

My goal is to have no visible scrollbar in both IE and Chrome until hovering over the inner div. Is this achievable? Thank you.

One potential solution could be:

.resize { 
    width: 500px; height: 350px;
    background-color: blue; 
    transform: scale(0.5);
    transform-origin: top left; transition: all 1s ease-in-out;
    overflow: hidden;

}

.resize:hover { 
    transform: scale(2); 
    overflow: auto;
}

The primary reason for the vertical scroll bar appearing in your initial state is due to the inner DIV (.scale) having a greater height than the outer DIV (.wrapper):

.wrapper { 
  width: 200px; 
  height: 200px; /* <---- */
  padding: 10px;
  border: 1px solid #888; overflow: auto;
}
.scale { 
  width: 400px; 
  height: 300px;  /* <---- */
  background-color: red; 
  transform: scale(0.4);
  transform-origin: 0 0; transition: all 0.5s ease-in-out;
}

To prevent the initial scrollbar, adjust the size of the inner DIV to be equal to or smaller than the outer DIV.

It's worth noting that there may be complications when the user tries to grab and scroll the content since the scrollbars are not part of the inner DIV. This can lead to the :hover effect being disengaged and the scaling reverting back to its original, reduced size.
