I could reproduce this problem as well.
isUserInteractionEnabled defaults to true. I can see that scrolling is intentionally disabled. I'm not sure what the reason behind it is.
See pull request #822. This resolves the issue.
This bug is fixed by reverting some old scrolling logic. But #882 is still valuable as it will allow us to reduce DOM complexity.
