This spawner does have a weird collision box. I can't build anything in the lower right corner (where the wall is missing)
It also looks weird with the wall to the right, and there's much space between the spawner and the left wall. Maybe the spawner could be shifted a few pixels to the left?

Yeah. seems to be almost 1 tile off

Thanks for the report, it is fixed for 0.11.9 by moving the picture of the spawner to the left.
