Rise 360 - Interactive Labelled Graphic does not work on mobile devices

Does anyone have a workaround for the labelled graphic not working on mobiles?

Due to the size of the item box that opens, the 'x' to close it is covered by the 'X' of the close course when on an LMS (it looks great on the Rise preview). I have moved the close course button on the LMS so it does not cover the item 'X' but it looks out of place and affects any courses using storyline.
