ViewAction closeSoftKeyboard() does ensure that soft keyboard is completely gone

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Soft keyboard enabled
2. EditText with focus to bring up the soft keyboard
3. Button that would normally get blocked by the soft keyboard
4. In an Espresso test, click on the button immediately after performing the 
closeSoftKeyboard() ViewAction.

What is the expected output?
The soft keyboard gets dismissed and the click on the button is successful.

What do you see instead?
On certain devices (physical Nexus 4 with API19 and Nexus 5 emulator with 
API19), the click is invoked while the soft keyboard is animating away despite 
disabling animations in the Developer Settings. If the click is done on the 
soft keyboard, a SecurityException will be thrown.

What version of the product are you using? On what operating system?
Espresso v1.1
Physical Nexus 4 Android 4.4.2 (API19)
Emulator Nexus 5 Android 4.4.2 (API19)


Please provide any additional information below.
The issue appears to be mitigated if I add a sleep of 500 milliseconds.
