This looks great, thank you so much for making a PR! Let's add a test case for this so that we don't ever regress on it in the future 👍

@marvinhagemeister I'm not sure how it would be correct to test the absence of an infinite loop, but I pushed a simple test similar to the original implementation, to test that getSnapshot can return NaN without causing an infinite loop.
