--- Comment #2 from Avner <avner.moshkovitz at gmail.com> ---
To simplify the debugging I replaced loading-from-zipfile with loading-from-external-url
To mimic the behavior of creating and cleaning object urls, I artifically 
clean the object url via revokeObjectURL, fetch the blob from the external url, and create an object url via createObjectURL

Ideally there should not be any memory leak as I'm cleaning the object url, but there is.  
After a finite number of images (~500 on my iPadPro), the load fails.  

An example of the problem can be seen here:
