GeoTIFF to ENVI GDAL translation causes rotation

I have a GeoTIFF(you can download it here ~16MB) which I want to convert to ENVI raw. I’m using this GDAL command:
gdal_translate -ot UInt16 -scale -of ENVI -outsize 1025 1025 dgm1_32372_5680_2_nw.tif dgm1_32372_5680_2_nw.raw
The command runs fine, but gives a warning:
Warning 1: Geotransform matrix has non rotational terms

When I compare the *.tif and the *.raw file in QGIS (3.14), the *.raw file got somehow rotated.
So I did some googling and found this question.
Ok, let’s have look:
grep "map info" dgm1_32372_5680_2_nw.hdr gives:
map info = {Transverse Mercator, 1, 1, 32371999.5, 5679999.5, 1.95121951219512, 1.95121951219512, rotation=90}

But according to this blog post the bug have been fixed with GDAL 2.20. I’m using GDAL 3.0.4.
So does anybody know what the problem might be?

gdalwarp -of VRT dgm1_32372_5680_2_nw.tif dgm1_32372_5680_2_nw.vrt

Creating output file that is 2000P x 2000L.
Processing input file dgm1_32372_5680_2_nw.tif.

gdal_translate -ot UInt16 -scale -of ENVI -outsize 1025 1025 dgm1_32372_5680_2_nw.vrt dgm1_32372_5680_2_nw.raw

Input file size is 2000, 2000
0...10...20...30...40...50...60...70...80...90...100 - done.
