21151	map.bern.ch returns PNG tiles when requested JPEG	habi	team	"==== What steps will reproduce the problem?
1. Download data in Bern, Switzerland
2. Load Imagery layer for ""Stadt Bern 10cm (2020)"": https://josm.openstreetmap.de/wiki/Maps/Switzerland#StadtBern10cm2020

==== What is the expected result?
Imagery shows up

==== What happens instead?
The imagery is not loaded, JOSM shows me ""Error: HTTP error 200 when loading tiles"" instead.

==== Please provide any additional information below. Attach a screenshot if possible.

Both ID and Go Map!! (https://wiki.openstreetmap.org/wiki/Go_Map!!) show the imagery just fine, JOSM doesn't.
I'm happy to provide more information on how to debug this and be able to load this imagery in JOSM.
