I have verified the fix with duplo-templates 5bc72cca5c6f44fd414bdffa62ff1c1ff1f549f8 (d15-4)

VS is no longer hanging when unfolding the template.

env info: https://gist.github.com/BenBeckley/ac1330570ab068386ce9d44d961a021a

The fix still needs to be verified with duplo-templates/master, then this bug can be marked as verified fixed.
