[tui][examples] Issue w/ right arrow key input ignored sometimes

[nazmulidris]

With the change removing Redux as the backbone, there is some strange behavior in examples that have the editor component where holding the Right arrow key will result in the caret moving a few columns and then stopping. The rest of the app seems to be responsive, but the arrow can only be moved that many columns to the right and no more.

Improve debugging and logging for when rendering errors happen. And figure out how to narrow down the problem listed above, and use a debugger to handle it.
