Series and Tooltip stacking order

I am using a combination of several Gnatt series and a Point series to show status over a period of time (with the Gnatt series) and specific events with the points.  I am using the tooltip to show detailed information about both the date range and the specific events.  My issue is that there is a disconnect in how the tooltips (via image map) and visual series are layered. 

For display purposes, the series are layered in the order they are added with the last added series sitting on top of the others, this is fine I add my range series first and then add the point series and they display as I want with the events showing up overlaying the ranges.  The problem is that the image map which is used for the tooltips is also assembled in the order the series are added, but in practice this has the effect of obscuring the poly used for the point tooltip underneath the poly for the ranges.

I can work around the problem by closing the point series and adding it as the first series and again as the last series so it shows up both with tooltips and visually.  Is there any other way to correct this problem?

Hello Andrew,

Indeed, this is the way the control constructs the tooltips at present. In addition to the workaround which you mentioned there is no other straightforward way to handle this.
