Issue Summary

Copying and pasting a Connect macro on the same page causes the pasted macro to not render a preview

Steps to Reproduce

1. Create a new page or open a page in the editor
2. Insert a Connect macro (such as /questions)
3. Copy the macro and paste on the line below

Expected Results

The pasted macro should display a preview like the original macro above it.

Actual Results

In the pasted macro, the preview area is blank and no iframe is rendered. On the published page, both macros render correctly, however.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
