How to prevent label/symbol duplication/cutting in Leaflet/Mapserver(WMS)

Question

As you can see the labels are duplicated and sometimes cutoff. That is because one tile doesn't know about the other tile. How can I prevent?

Disabling Partial labels helps a bit with the cutoff but the duplication is still there:

Thanks

Apart from @IvanSanchez's reply here: https://gis.stackexchange.com/questions/346467/preventing-clipped-labels-from-qgis-server-wms-in-leaflet-js.

You can actually set the tileSize to the width/height of your map and you won't have these kind of problems because the whole map would consist of 1 tile (although this solution will put extra strain on the MapServer). tileSize is part of the GridLayer definition: https://leafletjs.com/reference-1.7.1.html#gridlayer.

Param: tileSize
Default: 256
Type: number|Point
Def: Width and height of tiles in the grid. Use a number if width and height are equal, or L.point(width, height) otherwise.
