Once content has been drawn another pass through layout is required
to set mHasContent in the LogicalDisplay. Previously this pass was
occuring because of a delayed animation step. When timing of that
step changed that pass occurred before the draw completed. This is
why Presentations were immediately displayed in jb-mr1 and not
jb-mr2.
Fixes bug 10154780.
