reduced test case with comments

I've been looking into this bug and have a question.  What is the expected
functionality of execCommand when there is no "contenteditable" field and
"designmode" is off?  Should it do anything at all in this case?  Should only
certain commands be allowed to execute?  I know there is a command table with
specific "enabled" checks specified in it, but is it correct for the undo case?
 enabledUndo seems to only call "canUndo" on the frame; shouldn't it also be
checking if enabledInEditableText?  I.e., should undo be disabled for the case
when there is no editable field or we're not in designmode (as in this test
case), or does it need to function (and the crash really need to be fixed)?
