Updating 3D Tiles style doesn't always update existing tiles

[mramato]

The above image has a single 3D Tiles tileset being styled with a single green/peach style.

The differently styled data blue/white/beige data is the previous style I had applied which Cesium failed to update.

I don't have a reproducible test case yet, but it looks like it has to do with cancelling a camera flight mid-style change. Trying to write up a Sandcastle now.

Okay, here you go: Sandcastle

1. Run the Sandcastle and pan to Central park, allow everything to finish loading. Here's the view I used

2. Hit Fly to. The flight will start and you'll see styling is half-changed. Hit cancel and the unchanged tiles will not update to the new style

The demo has requestRender set, but I confirmed it happens in both cases.

My guess it's related to flight preloading? @loshjawrence @lilleyse any ideas?

Another data point - calling tileset.makeStyleDirty() has no effect. We'll look into it.
