Hide Finesse Gadget Header/title

[SakethN]

Hi,

I'm trying to hide the "Supervisor Assist Gadget" title for the Finesse 3rd party gadget.

In the gadget xml, I removed the title by which I was able to hide the gadget title and the text moved up to where the title is but now I'm getting empty space where the text was previously. 

And I'm not able to reduce the height by setting the height in gadget xml-
<ModulePrefs title=""
description="VisualNotification"
height="50">

and in the gadget script init()-
gadgets.window.adjustHeight(50);

How can I remove the excess height being observed? please suggest.
