Host fragment resize or scroll issue

[KoshkaRU]

In the "Navigation advanced sample" project.

When you try to register new user.

1. Click register.
2. Click inside the "Name" field.

Now you cannot see other fields because of host fragment cannot scrolling or resize. I have the same problem in my project. Tried to play with scrolling options and layout constraints. Bottom panel feel that the Input service start to work and move bottom nav panel on the top of the onsceen keyboard (in this sample it's hidden). But navigaton fragment (and fragment inside of it) cannot be scrolled or resized!
