Well, I was referring to the built-in browser spellcheck and the X windows copy/paste. Both of those probably rely more heavily on normal native widgets. Not saying it is impossible of course. The X windows copy/paste could be done using the invisible text approach firefox uses in PDF.js. That would also help with accessibility somewhat. But I'm not sure how they could integrate with browser spellcheck without basically going back to a less canvas-y approach. Invisible text areas surely would have layout problems aligning with the rendered font. But, I guess we'll see. I'm guessing Linux users are not a major factor in their decisions though. Firefox users probably even less so.
