Preinitialize javascript op

Hey everyone,

i am using a svg lottie animation in my loading screen for a website project.
The problem is that the ajax node, which parses the json for the lottie, is initialized pretty late in the loading process, so that the lottie just appears at the end for a short moment, before the loading screen is turned of anyways.

So my question is: is there a way to pre-render an op?
I already inspected the op Object in the console and found a prerender attribute.
I just tried to put op.prerender=true inside the op but it didnt help…
Cheers, joscha
