Idk about the actual website and how to stop it from happening.
But if is any help, this doesn't happen to me while using the app. I am using Jerboa on android. good luck
Hope it goes well.
The sublemmy for Jerboa is pretty helpful ; there is still features in the works so is pretty basic right now which is not bad but you know ; i would really like to sort comments in post , i shall patiently wait.
