Sorry for the big bounding box.
I missed that https://www.openstreetmap.org/node/1088752112 was also selected in JOSM while doing a 'search and replace'.
Since the block was besides a railway anyways and hasn't been touched in 12 years (https://www.openstreetmap.org/node/1088752112/history), I removed it after this changeset in https://www.openstreetmap.org/changeset/140000109
