The tile cache at that point has already sliced all the polygons
and lines to get a centroid that sits within the tile (since the tile is
the whole rendering request from the renderer point of view).
It's going to get ugly.

Better use your time to slice the styles instead and generate a
label layer on top that has labels rendered un-tiled
