Subject: [PATCH] Tweak the pre-processor condition, for Node.js environments,
 in the `animationStarted` helper (issue 13057)

While it's still not entirely clear if this would've prevented the issue as reported, given that the particular use-case reported apparently no longer applies, this small change really cannot hurt in general *and* it won't effect "regular" viewer builds in any way.
