This bug persists for a longer time and may or may not have been reported (or caught in your own internal testing) before:
The virtual boxes that comprise the layout do not stack side by side on Chrome under Windows, but take their position in own rows, thus most often being totally out of sight (but for a long scroll to the bottom of the page) - see e.g.
- note I narrowed the search to two hits in order to have a chance to see the lefthand box -
The bug also affects the righthand box when displayed:

I can confirm that the boxes work nicely on IE 9.
This bug reduces the ability or convenience of search filters (new users of the website won't even see it's there) and also takes away the important information "This title is included as a part of the following collections". It may even lead experienced users to wrongly assume "no one bought it and bought anything else" - so please fix this.
Thanks,
Mick
