The latest version of cesium(1.89) cannot load the 3dtiles model #10080

Previously, 3dtiles can be loaded in version 1.63.1. After upgrading to 1.89, the same 3dtiles model cannot be loaded

Hi @Makabaka-goodnight, would you be able to provide the dataset which is having issues? Is the tileset hosted on Cesium ion?

I'm very sorry to reply you so late，The dataset is on my local server and not on Cesium ion。

@ebogo1 Could you please check this model and see if you can determine the reason its no longer loading?

I tracked the error to this PR - https://github.com/CesiumGS/cesium/pull/9778 - this looks like it started after we updated the Draco version, maybe related to https://github.com/CesiumGS/cesium/issues/9847 but with models instead of point clouds. This might need some more digging to figure out where it's going wrong. This is a regression from 1.85.
