We decided to temporarily back out the new tab animations until we're able to do more user testing and validation of the new animations. While they may have some potential perf wins on the book, it's less clear if it can be perceived as an improvements, and UX doesn't think the new animation as implemented is as pleasing as the existing one.

Since there are a few bugs to be fixed with them, and we'll put engineering efforts on hold until we have new directions to continue, it's better to remove them from the tree so that people don't get stuck with them (and e.g. bug 1526112) for too long.
