Rendering errors when embedding Tableau dashboard in expand macro

[Chris Williams]

I am using the "copy embed code" feature from Tableau to show different dashboards on a confluence page using a custom macro (HTML macro disabled).  When the macro is configured on the page, it renders fine.  When I include it in the expand macro, some dashboards don't render correctly.

Not knowing much with JS/HTML, I don't see anything obvious when looking at it in the browser IE Edge Developer tools.  I tried it in Chrome and Firefox and the same thing happens.  I did find this post in the Tableau Community - Dashoard Layout Issues When embedded via Tableau for Confluence | Tableau Software

Update: It seems like the expand macro is sending something to the Tableau Javascript function that the screen size is small and it is trying to render it in mobile mode.  When the expand macro is expanded, it still thinks the screen size is small and why it looks like the mobile version of the page vs. desktop.

Any thoughts on what to look at next??

Thanks

Chris
