Links not properly copying/pasting in certain sitch

I've got an odd issue going on, not sure if anyone else has noticed this.

In my system, I use CKEditor in a few spots. One is where users can edit content of a particular type. This page serves up two instances of the editor - one for a "summary" content and one for a "full" content. (It's a content model like many online publications, where you have a teaser and then you click through for the full thing).

When firing up a new set of content (i.e. empty editors), you can add content to the top editor fine - make some content linked, etc. But if you copy that content and then paste it into the second editor instance - the links don't carry over.

BUT - if on the first editor instance, once your content with links is in there - you click the "Source" mode on, and then off again - no interaction with the code - and then copy/paste, the links carry over fine.

It seems like when setting up links in the content, the copyable content doesn't get updated properly until you do something to trigger it (i.e. flipping source on/off, for example).

When editing existing content (i.e. content with links already present, loaded from DB), the copy/paste between editor instances works fine as far as links copying over.
