Unhandled promise rejection: undefined thrown in CI

[ggetz]

I'm seeing some intermittent CI failures in the release test task (but not coverage) which appears to be due to a race condition in the Cesium3DTileset specs:

  Scene/Cesium3DTileset
    ✗ verify statistics
	Unhandled promise rejection: undefined thrown

I've noticed this one happening again more recently

These seem to be much more frequent than "intermittent" lately. I feel like I'm re-running a job almost daily because of this one "verify statics" test failure. any chance we can try and track this one down soon or exclude it completely until it can be fixed so we can rely on the little red X from CI actually being an error more?

Let's exclude it for the time being, but leave this issue open to track the problem.

Been seeing more of the other "statistics" tests failing apart from the one I already excluded
