Incorrect scrollbar position after restricted scrolling
Submitted by Egmont Koblinger
Produce at least a screenful of text so that the scrollbar is active. Then enable restricting scrolling, with the upper bound being the topmost row, e.g. echo -e '\e[1;15r'
Produce more output so that the cursor hits the boundary at the 15th row and the content starts scrolling. The scrollbar starts wandering upwards, though it should stay at the bottom.
When you try to scroll by Shift+PageUp or by dragging the scrollbar, suddenly everything jumps back to normal.
