Strange behaviour saving odt with svg in writer

The attached odt file contains an svg image.
When I copy this image (click on image, CTRL+C, then CTRL+V and move the copy) everything seems fine. Even when exported to a PDF the vector content remains. But when you save the file, close writer and open the file again, the copy of the image has been converted to a bitmap image.

Is this behaviour intended or is this a bug?

Unfortunately, today it works so. There is a bug about it in bugzilla

Thank you for the info.
