In the attached document, you can create a selection starting inside an input element and ending outside of the input element by a mouse drag.

This is not a regression from Safari 5. I actually wonder if it's a bug or intended behavior.

I don't think this can be an intended behavior.  SelectionController has a selection that crosses the shadow boundary.

For what's worth, window.getSelection().toString() returns "" and baseNode and extentExtent of DOMSelection report incorrect nodes.

DRT test

Here's a half-baked DRT test.  I'm going to abandon this test and write a bunch of pixel tests because it can only indirectly check the behavior and it's not suitable as a regression test.
