23779	Support TILED WMS parameter	BathoryPeter	team	"QGIS supports the non standard `TILED=TRUE` which instructs the rendering engine to add a buffer around the requested box.
Documentation: https://docs.qgis.org/3.34/en/docs/server_manual/services/wms.html#wms-tiled

Since JOSM queries WMS in tile grid, anomalies may appear at tile boundaries in some cases (eg. for long texts).
For example check the ""Magyar Közút / Buszmegállók"" layer of WMS https://map.cartographia.hu/wms/osm-kozut somewhere in Hungary.

I recommend always sending `&TILED=TRUE` parameter for GetMap requests.
