I do not think this a bug, it's just a ..."special feature". ;-)

During INPUT the 35s is in a different state than normal. The current value of the prompted variable is displayed and stack lift is disabled so that a new user entry overwrites the value in the display. You can even do calculations while the prompt in the upper line remains active. At this point the arrow down key obviously does not work as usual.

But there's a simple workaround. No need to insert meaningless instructions in your programs. Simply cancel the pending INPUT with the [C] key before entering something (or continuing without input - this works as well). After this pressing the arrow down key displays the next step, as usual.
