Make sure tab strip updates are committed after rotation
On lollipop version of Nexus 10, tab strips disappear if
you launch a new tab (and native page is shown), click on the URL
(or some other input forms), and rotate the device.
For some reason cc layer thinks that there is nothing to be committed after
we rotate and update the bounds. Probably we're updating the properties
even before actual rotation is made, and then after rotation the updates
are ignored.
This is a workaround to fit in M44. InsertChild() forces full tree sync which seems to fix the issue.
