User Macro for Vimeo is causing problem

[Mike Buchanan]

We had been using the Widget connector to display Vimeo videos but the videos will not play on Macs.  This link describes the bug

https://jira.atlassian.com/browse/CONFSERVER-52663

In the comments section, was a workaround, a User macro to display Vimeo videos.  This is the code for the macro:

## Vimeo video macro
## @Param URL:title=Video URL|type=string|required=true|desc=Enter the full Vimeo URL (e.g. https://player.vimeo.com/video/223136582 )
## @Param Width:title=Width|type=int|required=true|default=640|desc=Player width in pixels (e.g. 640)
## @Param Height:title=Height|type=int|required=true|default=360|desc=Player height in pixels (e.g. 360)

<iframe src="$paramURL" width="$paramWidth" height="$paramHeight" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

The macro works great in production, but on a QA test site, if I insert this macro, the top menu bar and left side bar become a gray color, the page view in the left side bar disappears and only the first Vimeo macro will display.  Nothing under the first Vimeo macro will display.  I have checked my stylesheets and custom html and they are identical on both sites.

This is only happening on our QA site.  But I would sure like to figure out what is going on so that I can make sure it doesn't happen on the production site.  Below are screen shots showing the QA site and the production site.
