Bug 461853

SUMMARY
***
MS People Tags with no face region are not read when image contains face rectangles with no names associated.
***

STEPS TO REPRODUCE
1.  Load attached sample file - test.jpg

OBSERVED RESULT
- No digikam people tag is generated, even though the MS People Tag "Mildred" is contained in the file.

EXPECTED RESULT
- People tag with no face region associated "Mildred" is read.

SOFTWARE/OS VERSIONS
Windows 11

ADDITIONAL INFORMATION
- I replaced the image file / xmp block with another image given that the original had faces I wish to respect their privacy.
- The MS People Tag XMP list block in the sample file is as follows. Note that there are empty face regions, and a name  (PersonDisplayName) "Mildred" with no face associated. This behavior is completely valid in the MS People Tag spec and was created using MS Windows Photo Gallery.
