Ng-click on icon does not get called when near ion-scroll

I am testing on Chrome with Ionic, v1.0.0-beta.13

When I have a div like:

    <i class="icon ion-more h3 ZEBRA" ng-click="abc()"></i>
            <div class="list card">
                <div class="card box" ng-repeat="box in data"> .....
                    <div class="item box-line" ng-if="box.showThis" ng-repeat="line in box.lines">
                        <span class="box-line-amt">{{nFmt(line.value)}}</span> ....

then the ng-click() does not trigger. If I replace ion-scroll with, say, a div, the mouse click triggers. What gives?
