Reactive matrix with <... matrix={matrix} matrixAutoUpdate={false}/>

[mordv]

What's the proper way to make a reactive matrix for an object? I once saw at some discussion that one can use:

  <group matrix={matrix} matrixAutoUpdate={false}/>

And expect it to react to matrix changes.

However, it causes very strange behavior. Here's the example: https://codesandbox.io/s/matrix-test-fr4gj?file=/src/Test.js
