Yes.

That's the answer I expected.

I think that's an important point.

<multicol>
  ...
  <div style="margin-left: 3cm; margin-right: 3cm">
    ...
    <figure style="margin-left: -3cm; margin-right: -3cm;
                   float: snap(0)">
       (intended to fit to the column width, 
       but when this becomes a page float, 
       the width will be too big)
    </figure>
    ...
  </div>
  ...
</multicol>
