Cannot scroll in issue board’s lists on iPad

I have created a board in a personal project, added enough tickets to a list so that scrolling will be required to get to the bottom of a list.
Instead of scrolling the list, the issue touched will be dragged. I have tried other gestures like 2-finger drag, trying to hit the tiny space between ticket, …, but no success.
Using the touch-pad on my keyboard attached to the iPad and the scroll gesture works just fine.
Scrolling using touch on the screen also works fine when I e.g. go to another project’s board. I went to one of gitlab’s boards. I cannot drag an issue there of course, but the lists there scroll as I would expect.

Am I doing something wrong?
I am happy to raise a proper bug if it is an issue and not a user error.
