The issue with the following code, when placing new blocks in a grid so that:

Occupied spaces are properly skipped.
New blocks are placed in the next available position rather than stacking.


When placing a new block, we should avoid simply moving to the next available row position but also consider skipping occupied spaces 
correctly within the method.

If a row is filled to its maximum height, the block must continue to look for the next available space in the next row until it finds a 
suitable position.
