When we use ui-mask in our angular application….
IE browser having issues like
1)Input event will be fired (like required) on page load itself and it will make form dirty
and 2)If we use multiple fields with ui-mask in a form then,last field with ui-mask will be focused on page load.
We can fix this issue by changing modules/mask/mask.js file.
