How to use InstancedBufferAttribute with Uint8Array?

I’ve found that when I put Uint8Array into the InstancedBufferAttribute,
WebGL fired an error for an invalid type.
However, it works with Float32Array.

I know we have UInt8BufferAttribute but are there any ways to achieve this in InstancedBufferAttribute.
It will save me tons of memory.

I added uint8 and its working

Please always demonstrate such issues with a live example. I’ve used webgl_buffergeometry_instancing as a basis to show that using Uint8Array works.
