Extraction Line Canvas missing from Experiment Editor after recent update

[cmmercer]

Recently pulled some updates on dev/dc (commit: 3c9bfb8). When opening the Experiment editor, the extraction line canvas is no longer showing by default. When I reset go to Window > Reset Layout, the canvas panel appears at the bottom but needs to be dragged to become visible. When resizing I get this error (log file to follow):

The error does not seem to be a show-stopper; I'm still able to run an experiment queue.
