<pre>For reference, here is a log from adding console.log calls to the original
code. From this can be seen that when I type the keys a ¨ e b , for some reason
the keydown, keypress, and keyup events for the b and c keys arrived in
duplicate, nested. That caused the b and c characters to be entered twice into
the document. What caused this duplication is unknown. Possibly some bug in
iOS, possibly some bug in the app (loleaflet) code.

When I tested with an extremely minimal HTML page with some Javascript to catch
keyboard events, I did not see any corresponding duplication, which would seem
to point the finger at our code... But no idea really.

console.log('textInput: "' + e.data + '"');
}
var inputeventhandler = function(e) {
console.log(e.inputType);

window.addEventListener('keydown', keyeventhandler);
window.addEventListener('keypress', keyeventhandler);
window.addEventListener('keyup', keyeventhandler);
