Remains of selected table, stay in edit area after inserting form element

[Krzysztof Studnik]

Environment

IE9, IE8, Opera11

TC

• clear editor contents
• insert default table or template with table
• select all (ctrl + A or selectall button)
• insert form or other form element

Expected

Selection is replaced by <form></form> element. It works this way in FF3.x/4, Chrome

Actual

Remnants of selected table stays in Editor area:

<table border="1" cellpadding="1" cellspacing="1" style="width: 500px;">
	<tbody>
		<tr>
		</tr>
	</tbody>
</table>
<form name="te">
	&nbsp;</form>

Propose of making the selection::getRanges return value READONLY, this's to eliminate any less disciplined plugin which make modification to a copy of public instance (selelction._.cache.ranges).

Note that we should enforce this semantic even if possibly a lack of back compat may be introduced.
