423a55dc test is unsolvable, skew

Problem

ARC-Interactive

The reasoning seems to be like this:

• The bottom line of the orange shape stays where it is.
• One line above the bottom, is moved one cell towards the left.
• Two lines above the bottom, is moved 2 cells towards the left.
• 3 lines above the bottom, is moved 3 cells towards the left.
• There is no wrap around, so when the orange shape overflows the left edge, the shape doesn't reappear on the right side.

Following the reasoning, the prediction is:

However the expected output is supposed to be the following. I have highlighted the problem area.

Solution

Replace the test output, with my prediction. So this task is solvable. Otherwise I doubt this task will be solvable.
