Are you a programmer? If so, the code is open source, so you could try fixing it on your own; it doesn’t seem that hard to fix. You could try to find where they are handling scroll input and see if there is anything that tells you what direction it is. Then if it’s horizontal just ignore it.
I see 306 issues and 0 pull requests. That’s got to be a bit discouraging as an open source project maintainer - plenty of people filing bug reports but no one that cares enough to help fix the bugs.
