After the video interstitial is closed, there is a new space at the bottom of the KeyboardAvoidingView.

# Bug Report

video interstitial

**Current Behaviour**
If there is a KeyboardAvoidingView component on the screen, after the video interstitial is closed and the keyboard appears, a new space is created. Interstitial ads without video do not.

I tested on react native 0.63.4 and 0.64.0.
and I am using latest version of this libaray.
