[Mesa-dev] CompressedTexImage3D spec bug?

Accidentally, I stumbled upon this bit in gl 4.5, chapter 8.7
"Compressed Texture Images":
"An INVALID_OPERATION error is generated by CompressedTexImage3D if
internalformat is one of the EAC, ETC2, or RGTC formats and either
border is non-zero, or target is not TEXTURE_2D_ARRAY."
This forbids TEXTURE_CUBE_MAP_ARRAY as a target.
Doesn't look like that's what mesa implements, nor does it make sense.
This has to be a spec bug, right?
