Unable to properly copy content between rich text editor windows without introducing bloated code
Anytime we bring new content into Marketo - specifically into the rich-text editor - we always first copy it to Notepad and then copy/paste it into the editor (CTRL-SHIFT-V doesn't always paste as text properly). But if all we need to do is copy content that's already in Marketo to another asset, I would expect the pasted content to be exactly what was copied. That's not happening - a kinds of bloated code is being introduced.
Here's the source copy:

and the underlying HTML:

Now when the content in the RTE is selected and copied, here's the pasted content:

But this is what the underlying HTML now looks like - notice all of the additional code?

Is this expected behavior? @Justin Cooperman
