📜 Description

Don't allow height to be 0 when KeyboardAvoidingView has behavior="height".

💡 Motivation and Context

The problem is that when we apply {height: 0} and then apply {}, then view doesn't reset its styles.

To overcome that problem I decided to avoid cases when we apply non-positive height (i. e. <= 0).

Closes #949

📢 Changelog

JS

• add height > 0 condition;

🤔 How Has This Been Tested?

Tested in example app.
