EXIF data in PNG images ignored

It seems that the EXIF data from the PNG images are ignored. The albums with the PNG data are generated without the date, although the PNG images contain the corresponding information. Also the EXIF info is missing for the images of the album.
According to the release notes the EXIF from PNG images are supported since version 23.

JAlbum version: 25.0.6
Skin: Tiger/Linen

See the URLs:

https://www.brango.sk/album/2005/20050502-museum-insel-homroich/index.html (the album contains PNG images and the date is not generated)

PNG files don't really contain EXIF information. The PNG standard includes some metadata "chunks" that are sometimes used to store similar information, but it's not in the EXIF format. And most of the EXIF fields would be meaningless in a PNG, since they relate to the camera settings. I'm not aware of any camera that takes PNG images.

It's all a bit murky:
