--- Comment #1 from Kimmo Kinnunen <kkinnunen at apple.com> ---
Thanks for the report!

As per the spec, it appears that compressedTexSubImage2D does not support COMPRESSED_RGB_ETC1_WEBGL

https://www.khronos.org/registry/webgl/extensions/WEBGL_compressed_texture_etc1/

> Compression format COMPRESSED_RGB_ETC1_WEBGL may be passed to the compressedTexImage2D entry point. 

> Revision 5, 2014/03/07
> Remove ability to use the format with compressedTexSubImage2D, as per the GLES extension spec.

Closing this as invalid. If I've made a mistake, please reopen.
