Embed Wave Dashboard in to Visualforce with more than one filter

gistfile1.txt

Here is the code example straight from the documentation that does not work:
filter="{'Sales_YOY': {'Account__c': ['{!Account.Id}']}}"

Here is the code from the 'bug' page that works:
filter="{'datasets':{'Sales_YOY':[{'fields':['Account__c'], 'filter':{'operator': 'matches', 'values':['{!Account.Id}']}}]}}" 

Here is the code that works for multiple datasets:
filter="{'datasets':{
                        'Sales_YOY':[{'fields':['Account__c.Id'], 'filter':{'operator': 'matches', 'values':['{!Account.Id}']}}],
                        'Sales_Daily':[{'fields':['Account__c.Id'], 'filter':{'operator': 'matches', 'values':['{!Account.Id}']}}],
                        'Open_Orders':[{'fields':['Account__c.Id'], 'filter':{'operator': 'matches', 'values':['{!Account.Id}']}}]
                        }}"
