[PaymentSheet] Fix issue opening the keyboard with small form

[michelleb-stripe]

Summary

When google pay is not available and a single LPM with a single input field is shown, when the keyboard is open it is immediately dismissed. Upon investigation this is because the bottom sheet size goes to 0 - clearing the focus of the field prior to bringing up the keyboard.

Motivation

#4570
