When you create a stacked group, resize the group such that the aspect ratio changes, but the group remains stacked. Note that the "expand stack" button moves around with the stack. It should remain centered along the bottom of the group in between the "new tab" button and the resizer mark.

This, although small, definitely blocks final release.

I'm worried about the number of blockers we're taking on tab candy, and how they divide into visual polish and functional polish. Speculatively blocking on this, but I'd kick it out of scope in favour of functional blockers, for sure.

Expand button is now centered under the stack.

http://hg.mozilla.org/mozilla-central/rev/14e4622db30f Sean, a couple comments on the patch for check in: * Please list your email address in your user specification (right now it's "Sean Dunn <seanedunn>", should be "Sean Dunn <seanedunn@yahoo.com>"). * The commit message needs an "a=", otherwise mozilla-central rejects it. In this case it would be "a=blocking". I've fixed it in this case; just for future reference.
