Several widgets in corral duplicate sidebars wrappers

Hi,

First thanks you for this excellent plugin.

I have a minor ‘issue’ :

I’m working on WordPress 4.0 and my theme define several sidebars.

I use the “setup theme” to automatically create corals for each sidebar : no problem!

My “issue” is this :
When I add several widgets to the same coral/sidebar, the sidebar wrappers are duplicated around each widget like this :

<div class="mysidebar">
	<div id="widget-1" class="widget">
		<div class="content">
			...
		</div>
	</div>
</div>
<div class="mysidebar">
	<div id="widget-2" class="widget">
		<div class="content">
			...
		</div>
	</div>
</div>

As I choose to put several widget in the same coral/sidebar, I don’t understand why the wrappers are duplicated.

What can i do to get the widgets rendered like so :

<div class="mysidebar">
	<div class="content">
		<div id="widget-1" class="widget">
			...
		</div>
		<div id="widget-2" class="widget">
			...
		</div>
	</div>
</div>

or even without the “content” div ?

Thanks
