UI-Bootstrap Popover disconnects from the screen

Question

UI-Bootstrap Popover disconnects from the screen

I am using Ui-bootstrap popover from UI Bootstrap (AngularJS).

and a popover on the border of the page seems to get off the screen ...

Is there a better way to position a popover - so that it stays inside the screen?

as you can see the popover is cut ...

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('PopoverDemoCtrl', function ($scope) {
  $scope.dynamicPopover = {
    content: 'Hello, World!',
    templateUrl: 'myPopoverTemplate.html',
    title: 'Title'
  };
});

<!doctype html>
<html ng-app="ui.bootstrap.demo">
  <head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.js"></script>
