With Page Previews on mouse-hover (introduced 2017-ish) this issue is semi-mitigated but continues to be an issue. It can still take many seconds to understand that the preview shown is for the very page you're reading. And if anything, the preview demonstrates that Wikipedia knows the link redirects back to this page, but is not smart enough to do anything about it.

Thanks Dbrant. Have you thought about how to prevent this from happening again in the future?

Me too, with Galaxy S22+, Android 12 (OneUI 4.1), same update build, also from F-Droid. I'm not sure how to get the crash report (stack trace) but if the one already posted isn't enough to track down the issue I will try harder.
