The icon of the fab is shown as background for the toolbar.

[arturs105]

This problem occurs when the following actions are executed:

1. Change the icon of the fab with fab.setImageResource(int res)
2. Call fabLayot.Show() to transform the fab into toolbar.
3. Now the new icon of the fab will be animated and also stay as background for the toolbar

I have tested this behaviour on:

• Nexus 5 (Android 6.0.1)
• Samsung Galaxy Note 3 Lite (Android 5.1.1)
• Nexus 10 emulator (Android 4.4)

If android:background element is set for the toolbar, then the fab's icon won't stay as background for the toolbar, but the animation issue still remains.

This issue might be related to Issue on Sony Devices with FabToolbar, but this is a problem for more than just Sony devices.
