StrictMode and Mui Dialog breaks Resium

[Kai-W]

I have an app where Cesium/Resium is used to rendere 3DTilesets on an Openstreetmap in a MaterialUI Dialog. With React StrictMode enabled the first component doesn't get unmounted properly. https://codesandbox.io/p/sandbox/magical-christian-fqsxd6?file=%2Fsrc%2FApp.tsx%3A64%2C23

Inside the Dialog there are 2 instances of Cesium. First a broken one and below it is a second working Cesium instance

Tested on Windows with Chrome, Edge and Firefox.

Wierdly this only happens inside a Mui Dialog. Without the Dialog component Resium unmounts as expected

I've updated from [email protected] to [email protected] then I get a similar issue.

In strict mode, this occurs.

I'm not using MaterialUI Dialog but a custom tailwind component with an absolute div.

i tried to reproduce the problem without Material UI:
It seems the problem occures if there is a change in the component hierarchy

The new Resium Version seems to fix the duplication bug but moving the viewer to the bounding box works for the first render but breaks after a recreation of the viewer.
