Draco compressed output looks different compared to the original one

[sunyonglincanada]

Hi there,

I've tried to compress the original glb file but some tiles are missing when spinning or dragging the compressed model. Here is the codepen - https://codepen.io/sunyonglincanada/pen/MWjOOJZ

I've tried the same way that mentioned in #569 but it did not work. Any ideas to fix this issue? Thanks in advance!!
