fix typing event bug

[leonardo3130]

Fixes typing event bug accidentally introduced in #63 .

Important

I was not able to run the demo locally to check if other bugs are happening, but it should be okay.
@jonmbake if you know how to run the demo locally for testing/debugging please let me know so I can be sure to
not create additional issues.

@leonardo3130 To test locally:

npm run build
cd docs/demo
open index.html

@jonmbake I fixed another small bug, always related to event.preventDefault(). Then I also set cursor position to be at the end when navigating to a new element of the history. Let me know if something needs to be changed :)

@leonardo3130 There are a couple of other minor tweaks we may want to make in the future:

1. Input is not cleared when clicking down arrow while navigating history on first item is active.
2. Input is lost when navigating history.

The core functionality works; I'll create a separate issue for these minor changes.
