Subject: [PATCH] Bug 1463605 - Set mMayHaveOpacityAnimation and
 mMayHaveTransformAnimation flag to continuation or IB split sibling frames
 too. r=birtles

Without this fix layout/reftests/css-animations/ib-split-sibling-opacity.html
would have failed if the next change in this patch series is applied.
