FrameSelection::selection becomes invalid, because it returns true from isRange() in WebCore::EditorClient::respondToChangedSelection callback.
The following comment for VisibleSelection::setWithoutValidation may be of interest (or maybe not):
// FIXME: This function breaks the invariant of this class.
// But because we use VisibleSelection to store values in editing commands for use when
// undoing the command, we need to be able to create a selection that while currently
// invalid, will be valid once the changes are undone. This is a design problem.
// To fix it we either need to change the invariants of VisibleSelection or create a new
// class for editing to use that can manipulate selections that are not currently valid.
Varun: I think you ought to take a look at this eventually.

I think we've fixed this bug in the latest WebKit. Could you check that?
