Steps to reproduce the problem:
1. Install said extension or any keyboard from https://github.com/google/extra-keyboards-for-chrome-os
2. Turn the on-screen keyboard on
3. Try typing something with the on-screen keyboard

What is the expected behavior?
The letters you touch correspond to the letters that appear on screen

What went wrong?
The on-screen keyboard layout is US instead of Dvorak, but the keys triggered are the ones defined in the layout, as such typing is really difficult.

I'm the developer of this specific extension, based on the keyboards found at https://github.com/google/extra-keyboards-for-chrome-os and my layout has been merged in here. If changing the extension can solve this, this would be acceptable too, I just don't know how. For the related issue on Github, see https://github.com/google/extra-keyboards-for-chrome-os/issues/35
