## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Scroll assist does not run when changing keyboards. This means that
inputs can be hidden under the keyboard if the new keyboard is larger
than the previous keyboard.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- On Browsers/PWAs scroll assist will re-run when the keyboard geometry
changes. We don't have a cross-browser way of detecting keyboard changes
yet, so this is the best we have for now.
- On Cordova/Capacitor scroll assist will re-run when the keyboard
changes, even if the overall keyboard geometry does not change.


In the example below, we are changing keyboards while an input is
focused:
