Cannot disable notification "X is displaying over other apps"

[coolbigbear]

Hi, when sliding the notification left and clicking the cog icon the "Display over other apps" category of notifications appears but clicking it makes it disappear.
This is a confirmed bug, see here:

Is there any way to get around it?
