I found it myself:
Add a grid to a section 2x1 (2 columns, 1 row)
Add an image or so in the left cell.
Add a container to the right cell.
Add your bunch of text to the right cell.
Let it overlap on the bottom.
Now select container, go to inspector and goto Overflow Content
Select scroll and scroll direction Vertical.
Voila!
Great feature in Editor X!!
