Is a framebuffer with an invalid attachment invalid or incomplete?

Outside an rAF, the webgl textures associated with a layer are invalid (https://immersive-web.github.io/layers/#xrwebglsubimagetype). If such a texture is attached to a framebuffer, then what is its state outside an rAF? Also invalid? Or incomplete? Or...?

Related to #195 and #174.

Yes, this is related to #174.
I believe the consensus was that those texture should be detached at frame end.

And it's the content's responsibility to reattach them at the next rAF?

Okay, what about if the texture is bound with gl.bindTexture?

I believe so.
Do you want to take a stab at writing down the behavior? We could also work on it together.

Unsurprisingly, the recent announcements from Mozilla have derailed this. I will probably have a bit more free time in a bit, but right now I'm afraid I'm running round like a headless chicken.
