Use two IRWs in a sidebar – box size problem

I’m using twenty twelve and WP 3.5 and have tried placing two Image Rotation Widget:s in the sidebar (I assume first of all that this is supposed to work). All images in the one of the IRW has height 500 px (lets call this widget Widget1), and all images in the other widget has a smaller height of 193 px (Widget2).

If I place Widget1 somewhere below Widget2 (there can be other widgets in between, doesn’t matter) that space that Widget2 will occupy will be the same as the height of Widget1 ie there will be a lot of white space under the Widget2 images. (Like this http://flic.kr/p/dMStJm)

It all works great is Widget2 occures somewhere above Widget1.

Is this a bug – again assuming that this feature is possible.

Any solution to this? Thanks!
