In single Object, the Selection menu in goes below other chart nearby

The problem occurs when some charts are positioned just below other charts. 
You go to the dev-hub Single Configurator and display the sheet using the "view" button.  When clicking in the map the "selection options" that appears above the map are rendered below the charts. T

Step to reproduce

• Create a sheet in any Sense app containing a chart (for example a map) and some other objects (for example "Filter panes") just above the map.
• Go to the Singe Configurator (see this: https://help.qlik.com/en-US/sense-developer/November2018/Subsystems/Dev-Hub/Content/Sense_Dev-Hub/SingleConfigurator/dev-hub-single-configurator.htm)
• Select the App and the Sheet you created.
• In the "General" menu unflag all the options.
• Click on "view".
• Click on the map to do any selections. You see that the option that opens above the map are under the Filter Panes.

Environment:

• Qlik Sense 2018  September and November release.
