Changing iframe URL to another protocol reloads the page, but not when
fired from a timer

My theory is that later incarnations of Chrome@Android stops the behaviour
below when not "user triggered".
My question is if anyone has found a work around.



Setting src with another schema on an iframe makes the device open an app.
Well.. it works for certain browsers@devices.
It has worked for "all" devices since a year but not since a while back.
It works when I trigger this event from a click like so:
(this works on "all" devices)
$("#myAnchor").click( function() {
$("#myIframe").attr( 'src', 'schema://redirect=whatever' );
});
But not from a timer like so:
(i.e. this works on ie10metro@win8, safari@ios and opera@android but not
chrome@android)
window.setTimeout( function() {
$("#myIframe").attr( 'src', 'schema://redirect=whatever' );
}, 1000 );
