[NEW CONTENT TYPE REQUEST] High Efficiency Image File Format (.HEIF)
Expected
Most if not all HEIF images are classified as sample1.heic: MP4 media file (video). I'm expecting a MIME type of image/heif and High Efficiency Image Format still (image).
Not sure if this needs to be a new content type or a misdetection so apologies if this is the wrong ticket type. It's close but possibly "inaccurate". Here is the output from exiftool with the source file from https://filesamples.com/formats/heic
