Drop-down lists in modals and dropdowns don't work correctly on iPad if ngTouch is a dependency

If you use a native drop-down list () inside a dropdown or a modal from angular-bootstrap and if your application has a dependency on ngTouch (1.4.3), the drop-down lists don't work as expected. When you click a drop-down list, the list with options blinks most of the time, making it very hard to choose an option. If you remove the ngTouch dependency, the drop-down lists work fine. I created a plunkr which demonstrates this issue: http://plnkr.co/edit/fsU1zKpwalrxEEelsBka. I'm using safari on an iPad air 5 (iOS 9.2). Could you please provide a solution for this issue? Thank you!
