Featured Image as dynamic source in output of a View missing on front-end if not first View on the page

Symptoms

The output of a View which includes an Image Block using Dynamic Sources that is set to output the featured image will fail (image is missing) on the front-end if there are other Views on the same page before this View.

Workaround

There is no workaround available at present.

This will be fixed in the next full update of Blocks.
