fix: ignore non-visible keyboard

[kirillzyusko]

📜 Description

Ignore non visible keyboard in KeyboardView.find() method.

💡 Motivation and Context

Sometimes we may have two keyboards:

And the current algorithm for a search returns an invalid keyboard (not a one that is actually shown on the screen):

or

But when actual keyboard is tracked, then the frame of this keyboard has non-zero height:

So to fix the problem with invalid keyboard view being found I decided to modify a condition and add additional condition to check that frame.height != 0.
