Report canvas backgrounds changed when publishing report to service

I just wanted to add that this impacted several reports I have also.  I have been using a custom JSON report theme.  However, the code did not include a triple wild card for color - but it did include a triple wild card for font.  I removed the custom report theme and the background returned to normal.  

However the alternative is to go to every page in your report and change the background color back to the original color (in my case white). 

Here is the code for my JSON file in case this helps with anything

{
 "name":  "Report Colors",
 "dataColors": ["#92d050", "#ffff00", "#ff0000", "#0081C6"],
 "background": "#ffffff",
 "foreground":  "#3A6108",
 "tableAccent": "#92d050"
}

"visualStyles": {
    "*": {
        "*": {
            "*": [{
                "fontSize": 12,
  "fontFamily": "Calibri"
            }]
        }
    } 

}

I am really unhappy with this change as it puts a big burden on me to get all of my reports updated.
