It is possible to scroll a List (or Combos dropdown) further than should be possible using the mouse wheel. It does not always work, so to reproduce the bug it may be required to move and click around the List a bit.

Tested with IE9 in IE7/8 compatibility mode.
Not reproduceable with RAP 1.5 or IE9 standard mode.

Fixed with commit 3f3d03457f3975c4e8111b5ac8005e11d1ec8bb1.

Took a while to figure out, but because the OUTER list item element had no overflow:hidden style set, the vml-element that renders the selection background (if it's a gradient) increased the size of the container, allowing the mousewheel to scroll further if one of the last few items was selected.
