<Snipped quote> The post scrolls fine for me when swiped (desktop version) - in my experience, catching a scrollbar is a lot trickier...

It could very well just be that Samsung's browser is a bit derpy in regards to scrolling individual forms, resulting in both my sig problem and the post problem. I'll try a third party browser and report back.

EDIT: The issue was in fact due to Samsung's browser. Firefox is allowing me to scroll as desired.
