TOPIC: z-index problem?

I bought the pro version hoping that the suspected z-index problem in this version would be OK.
In desktop mode, the tooltip overlays most items. However, this is not the case in all cases. Some layers still overlap the tooltip. The biggest problem is in mobile mode (see picture). Here the tooltip is at the lowest z-index. In the css file the z-index is at 50000 and 60000. This should be enough. Unfortunately this is not the case. It also seems that there are no changes when I change the z-index value.
Can anyone help me get the tooltip to the front in both desktop and mobile mode?
