Issue with live updates of tabs?

Seems like that live updates of components via dash_core_components.Interval don’t work in combination wth dcc.Tabs (Method 2: Content as Tab children). I’ve 2 callback functions each updating content in tab 1 and tab 2 respectively. Both callback functions are triggered via interval (with same frequency). However only the content of the first tab 1 is updated automatically. Tab 2 requires a manual page reload to update it’s content (plus navigating to tab 2 cause tab 1 is the default one). Is this limitation known? What’s an appropriate workaround?
