1.4.0 and 1.3.x - thumbnails of folders are upsidedown - Samsung S10 mobile only!

[masterjp]

Today I checked my photos from my Samsung S10 smartphone and detect a problem with folder thumbnails.
I use the single thumbnail setting for folders. They all have a wrong exif-orientation.
If I open the folder with the smartphone pictures, the thumbnails of the photos are correct!

So I think it is only a problem of the folder thumbnail generator. It maybe ignore the EXIF-orientation of the files.
