Thank you very much for the proper details, it helped me a lot!
I have identified the issue, there was indeed a problem where the script tried to recognize whether to initialize the back-button trigger. I have made a correction on the script directly via FTP, now it should work correctly after clearing the cache.
I will also make sure to include this fix in the upcoming release.Best,
