Losing line breaks when pasting code into Nitrous

When pasting a bloc of Ruby code from Atom or the Nitrous text editor into the Nitrous console, all line breaks are lost. Multiple lines of code are concatenated into one long string, separated by a space where the line break was in Atom.

For example, if these three separate lines are copied from a text editor (either in Nitrous or Atom):
pool.each() do |number|
remainder_3=number.%(3)
remainder_5=number.%(5)

This is what Nitrous displays after pasting:
irb(main):001:0> pool.each() do |number| remainder_3=number.%(3) remainder_5=number.%(5)

Here is what I want to happen:
irb(main):001:0> pool.each() do |number|
irb(main):002:0> remainder_3=number.%(3)
irb(main):003:0> remainder_5=number.%(5)

The Ruby tutorial I'm watching retains line breaks when pasting so either my Atom or Nitrous settings need changing. Can someone please clarify how this is accomplished?

FYI: I'm running Windows 8.1 and Firefox. Note that I have this same issue using Chrome.

Thanks in advance!
