However, mouse position detection appears to be attempting to factor in the transform. The result is that the options cannot be selected with the mouse - except where the area that the options should be overlaps with the area that they actually are. Then it is possible to select an option by clicking in the area it should be if the transform had been applied. Confused? Well try the attached sample and it should make sense. Reproducible: Always Steps to Reproduce: 1. Attempt to select an option in the the attached sample. Webkit and IE don't handle this very well either. Neither applies the transform (although IE does a better job of positioning the dropdown somewhere appropriate) but both are able to select an option.
