Shouldn't this still be INVALID_OPERATION according to the spec?

According to the core spec, any internalformat not in the list should generate
an INVALID_ENUM.  I think the ANGLE_depth_texture spec is incorrect.

OK looks like OpenGL 4 indeed says:
" An invalid value specified for internalformat
generates the error INVALID_ENUM"


But ES3 says this:
'Table 3.15 summarizes the
valid framebuffer and texture base internal format combinations. If the
combination
is not valid, an INVALID_OPERATION error is generated.'

ANGLE_depth_texture says:

    "CopyTexImage2D and CopyTexSubImage2D generate the INVALID_OPERATION 
    error if the base internal format of the destination texture is 
    DEPTH_COMPONENT or DEPTH_STENCIL_OES.

And WebGL says nothing about it.

So I guess it doesn't matter :)

Done.
