Steps to reproduce

1. Upload a image to Assets
2. Output the width/height of the image by ftl (or export the asset in XML)
   

Expected results

The width and height of the image should be set.

Actual results

The width and height are set to -1

Workaround

Open the image in the dam-app and save it. Then the width is saved correctly.

Development notes

The new upload dialog introduced with 6.2.43 seems to not save the widths of the images.
This can be reproduced on demoauthor. Just upload an image to DAM, export it as an XML. There you see width propterty set to -1.

See attached XML. See attached screenshot of the XML file exports.
