When entering a comment, the text field is taller than one line, but the text never wraps. It scrolls horizontally on a single line instead, which is quite frustrating if you are trying to scan for mistakes before you post, edit something, etc.
This only happens in landscape mode. In portrait, the comment box starts as one line, then auto-expands and wraps as it should. In landscape, it starts multi-line and never uses any but the first. Similar text fields in other apps wrap just fine, so if it's something particular to my phone/version, it only seems to happen in the SE app.

I tagged this as a bug because I feel it's just wrong. If this is intended behavior, let me know and I'll change it to a feature request.
