Image upload stuck with "Processing" message

[jaffadog (Jeremy Waters)]

@anon73664359 thanks for the heads up. I just tried disabling " composer media optimization image enabled" in settings and uploading larger files now works. Sounds like this is a client-side component. I am not seeing any errors in the browser JS console. I think that I saw this might be a new feature in the release I am running. Is this a know issue? Or should I file a bug?
