[Plugin: TinyMCEComments] blockquote in IE

I have noticed that this pluging doesn’t work properly in internet explorer when using the cite button.
When using this button, all the comment is quoted, instead of only the desired part. It is impossible to quote only par of the comment.
Is there any patch for fixing this?
