After JIRA upgrade and using Confluence EMBED in confluence no longer works

[Richard Romero]

Post the upgrade the EMBED Frame returns the following error. Both examples of embed frame failed from Portfolio Reports Embed and from Dashboard wallboard. These were working prior to Jira upgrade.

'This content cannot be displayed in a frame' 
To help protect the security of information you enter into this website, the publisher of this content does not allow it to be displayed in a frame

Versions: 
JIRA upgrade to 7.6.3
Confluence 6.4.3 

Verified:
Application Links verified connected
Confluence to Jira (OAuth)
Jira to Confluence (OAuth)

Reproduction Steps:

1. Create a Confluence page
2. Create an HTML macro
3. Edit the macro
4. Add an iframe to the macro:

Example:

<iframe src='https://jira.nordstrom.net/plugins/servlet/Wallboard/?dashboardId=29808' width= 98% height='225' style='border : 2px solid #6CA372;'></iframe>

Expected:

Dashboard will show up in the box embedded in the Confluence page. 

Results:

The box is empty (completely solid white).

It does not seem to work for the page include macro either.
