I use pinta on Ubuntu Linux and the same problem exists. I notice that it not just EXIF data, but all metadata stored in the photo.
I tested with a Sample image containing a large amount of metadata: EXIF, IPTC and XMP. In my case I simply used Pinta to rotate the photo 90 degrees and then re-saved it. All the metadata was lost in the process.
To confirm that the metadata was not in the resulting image I tested with several tools: EoG and exiftool,
