Module: Notification doesn’t hides

Hello. I use. Origination module with 3 icons:
1) friends requests
2) Conversations
3) Global notifications.

Problem appear only with #3 notification on mobile:
1) press on bell icon to open notification list
2) Press on MENU icon
Result: Site menu is opened, but notification list is still on top (over menu).

To hide notification list I have to press Bell icon again.

Expected result: Notification should hide automatically when I press anywhere outside it.

Friend request list and conversation list working fine and hides after I open menu.

Thanks.
