Got curious so opened the link, waited to load, and pushed back. It worked without issue This is with Firefox on Android, and the uBlock add-on. I tried again, this time with uBlock disabled. It took like 30 full seconds to load, but still the back action worked fine... so it must be an issue specific to Safari.
