Is that satire? It created a whole browser and server environment just for suggesting overflow-x: hidden?

That's supposed to be junior level capabilities.

I called it fascinating and used it as an example of Fable being "relentlessly proactive".

Maybe it's a difference of perspective, to me it's a model failure and certainly not proactive.

I also see this as a model failure. In this particular example the proactivity was a negative trait!
