--- Comment #19 from Mads Erik Forberg <mads at langesund.org> ---
While testing, I discovered the way that's the easiest to reproduce this:

1. Start a new tab session in Safari
2. Navigate to https://www.vg.no/?ios-bug=true (where the workaround is disabled)
3. Scroll down to a teaser / link a bit out of the first viewport.
4. Swipe / navigate back / use history back and the bug will trigger.

The clue seems to trigger more often when the browser / tab session is "fresh". I'm able to reproduce the bug on multiple devices, both physical and via emulation on BrowserStack.

I hope this will make it easier for you to reproduce the bug.
