Cross-Original Read Blocking Problem

[mst94]

Hello,

when using the leaflet DWD map and clicking many times randomnly on the map, after some time a Cross-Original Read Blocking Problem occurs.

The console says:
jquery.min.js:4 Cross-Origin Read Blocking (CORB) blocked cross-origin response https://maps.dwd.de/geoproxy_warnungen/service/?REQUEST=GetFeatureInfo&SERVICE=WMS&SRS=EPSG%3A4326&STYLES=&TRANSPARENT=true&VERSION=1.1.1&FORMAT=image%2Fpng&BBOX=6.4273101159228405%2C47.4355191531953%2C18.05084527217284%2C50.324422739309384&HEIGHT=400&WIDTH=1058&LAYERS=Warnungen_Gemeinden_vereinigt&QUERY_LAYERS=Warnungen_Gemeinden_vereinigt&INFO_FORMAT=text%2Fjavascript&PROPERTYNAME=EVENT%2CONSET%2CEXPIRES%2CSENT&FEATURE_COUNT=50&X=420.9719503373341&Y=192&callback=parseResponse&_=1611062981598 with MIME type text/plain. See https://www.chromestatus.com/feature/5629709824032768 for more details.

The url request gives back an XML answer, I think this may cause the problem. I noticed the long float X-value and the rounded Y value in the URL request. After changing the X to an integer, the answer is JSON and seems right.

Stack trace of the console:

send @ jquery.min.js:4 ajax @ jquery.min.js:4 getFeatureInfoJsonp @ warnmod_leaflet-betterwms.js:39 fire @ Events.js:190 fireDOMEvent @ Map.js:1440 handleDOMEvent @ Map.js:1397 c @ DomEvent.js:92

I use the most recent leaflet version 1.7.1.

Thanks in advance
