Revert^2 "Make sure the parent change is set for changes with intermediate parent"

This reverts commit 9af48772.

Reason for revert: Reland CL

The previous submit caused test failure because it hides independent
closing window, but the surface wasn't got show in the following cases:
1. Recent transition without top Task change.
2. Recent transition with changing top split, the following transition
   doesn't include leaf task as independent change.
To prevent that, this CL remove the hide logic from the previous submit.
Will have followup CL to address the hide issue.
