Can't crop arbitrary selected pages in combined PDF?

I'm getting weird behavior or seeing a bug when I try to crop selected pages in Acrobat XI.

Steps:

1. Click Create->Combine Files into a Single PDF

2. Add files and combine them as usual

3. Click on the Page Thumbnails view on the left

4. Control-click on a non-contiguous selection of thumbnails

5. Right-click and select Crop Pages. Fill in all the details and click OK.

Expected: Only the highlighted files are cropped.

Actual: All pages between the first selected page and the last selected page are cropped, even if they weren't selected. Pages before the first selected page and after the last selected page are not cropped.

Is there a way to override this behavior so only the selected pages are cropped? In the crop dialog, I can select all pages or a contiguous range (with the even and/or odd options), but no option for just "selection" like the rotate pages option has.

Thanks.
