input loses focus when re-rendering contents

In an attempt to implement a type-ahead search/filter on an input in the body of the app, the focus on the input is lost when the app renders refreshed content.


The goal here is to be able to have two or more search/filter inputs.

Start by reproducing the lost-focus behavior with a type-ahead search input in the app body, then inspect the rendering path that refreshes the content. Done means refreshed content preserves focus and supports two or more search/filter inputs.
