Describe the bug
For Checkpoint 3.1.12, which initially displays with premises on left and responses on right, after interacting with the question then navigating away and back, the question display has changed to show premises on top and responses on bottom, which is slightly disorienting. After interacting with the question again, the display snaps back to side by side.

Javascript Errors
Many many errors can be quickly diagnosed from the Javascript Console error log. On Chrome this is View --> Developer --> Javascript Console, on Safari ⌥⌘i or Develop --> Show Web Inspector on Firefox Tools --> Web Developer --> Toggle Tools

Start by reproducing Checkpoint 3.1.12 on the sec-matrix-inverse page: interact with the question, navigate away, return, and compare the panel arrangement before and after another interaction. Trace the drag-and-drop question's display behavior during navigation, and consider the issue done when premises and responses retain the intended side-by-side layout after returning.
