Progress Bar Frozen On Chrome Browser

Anyone having issue with backup/restore or optimize database progress bar frozen on Chrome browser?

I just noticed this today and it was working fine a week ago. (Chrome browser version 83.0.4103.61)

Tested ok on Firefox and Microsoft Edge browser.

Updates:

CS-CART version 2.2.5 - OK
CS-CART version 4.3.4 - Frozen
CS-CART version 4.11.4 SP2 - OK

Yes see this in the blog

But I've applied the changes and it hasn't worked for V4.3.6

EDIT - The ol classic "try clearing all caches..." and now it's working with the changes from the blog.

Yeah, received CS-CART email about the fix too. updated the file and everything is working fine now.
