On the DevForum, on my phone, when I reach the bottom of post replies, the forum sometimes autoscrolls to the end of newly loaded content. This loops until all replies are loaded. It can happen on accident or on purpose. This may be an issue for all mobile users, or just me.
This has been happening ever since I first viewed the DevForum, before I even logged in.
To easily recreate this, open a large topic on your phone, and scroll all the way into the footer. Doing this causes this issue 100% of the time.
If you also get this on mobile, reply so everyone knows if this is a real bug or not.
