[Public WebGL] meaning of the specification of FBO sampling and interpretation by UAs



The ES specification states that the result of sampling from a texture attached to a framebuffer at the same time as sampling to that framebuffer is undefined.

Google chrome seems to interprete this as: If a texture is bound to any texturing unit while that framebuffer is used it's an error.

However a different interpretation of this would be: If a texture that is bound is actually sampled during the framebuffer operation it's an error.

Which of these interpretations is the correct one?
