Code/Raw panel does not display properly.

Since upgrading to version 0.5.3 (697), opening files only populates the preview half of Macdown. The code/raw side looks empty until you resize the split. Upon doing that, the code does reveal itself, but not if the code panel is less than 60% of the spit.

EDIT: This is on Yosemite.
EDIT2: This only happens when the editor is on the right.


Start by reproducing the issue in MacDown 0.5.3 on Yosemite with the editor on the right, then resize the split to confirm when the code/raw panel appears. Done means the code panel displays immediately at widths below the reported threshold without requiring a resize.
