Ionic Side Menu Disable Dragging When Open

My project uses a pretty simple side menu that I’ve modified with an ng-click function to apply a blur effect to the main content when the menu opens. I’ve used the drag-content=“false” directive applied to the side-menu ion-pane, which works as intended until the menu is opened. When the menu is opened I can then swipe/drag the menu closed. Is there a way to disable this behavior?

To provide more info, I open the menu through $ionicSideMenuDelegate.toggleLeft();
