The Customize Tab appears to not be a "normal" tab, and so the tab-sharing code is failing to render it to a canvas. All other types of tabs seem ok, including prefs, addons, about:home/webrtc/support/etc. Likely there's something "unusual" about the window and rendering for Customize that makes it non-capturable. Probably there's no easy way around this other than re-engineering Customize, or maybe having some custom capture code in the tab-capture code, once a way to capture it is devised. It's likely not worth a major re-engineering to be able to share Customize when everything else works; an alternative would be to simply ensure it renders a black/etc screen (text or a warning would be nice, but not necessary IMHO).

Thanks for triaging this, Randell! This might even go back into Hello's camp, because perhaps we simply need to exclude about:customize as a shareable target. That's perhaps the easiest fix right now.
