DO NOT MERGE: Revert "Don't let IME window fit status bar"

This reverts commit 3cd311415ba00d5d75660a8607d1ece5e68f0534.

Reason for revert: The CL causes the regression b/170474494
And it also makes status bar color incorrect while
FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS is cleared
Fix: 170474494

Change-Id: I26bed08456197721d07f2fab563be0c54e43efd2
(cherry picked from commit 427bdc1c86904649dc7c12cf917c05d61f2fe3fa)
