HTML5 File System Info Bar Not Responding In Kiosk Mode

HTML5 File System Info Bar Not Responding In Kiosk Mode

I am creating an application that runs in chromium portable in full screen
with the --kiosk flag. It is written in HTML, JavaScript, and CSS. I am
also using the HTML5 File System to store some large sets of data. The
application opens up in full screen, and the info bar to request permanent
storage pops up.
The problem is that, while running in kiosk mode, you cannot select either
"OK" or "Cancel" to the file system's request to store data. You can only
close the info bar with the "X". This results in the file system not
getting any kind of quota and the application fails.
So is there a way to have unlimited storage for an application running
from "file:///"? I have tried using --unlimited-storage but it doesn't
seem to work for a webpage.
Is there a way to open up in full screen without using --kiosk? Any other
work arounds or suggestions are welcome.
