Ajax File Upload is not working in the latest Chrome Version 83.0.4103.61 (Official Build) (64-bit)

Ajax File Upload is not working in the latest Chrome Version 83.0.4103.61 (Official Build) (64-bit) as the update has affected images/media widgets. The POST request to upload files shows as canceled and the upload fails.

When “iframeSrc” is set to “javascript:false” on https pages, Chrome now seems to cancel the request. Changing this to “#” seems to resolve the issue, but what other consequences might this have? Talk to our expert consultants to get this right.

Here’s what we do:

Patch existing jquery.form plugin or update to a newer version.
Test affected modules on Chrome version 83.0.4103.61
Test jquery.form functionality on all browsers.

This problem seems to go away if we ensure the iframe jquery.form uses for the upload has an src of # rather than javascript:false, which has been used for https requests for years.
