Not showing data if added in a mashup as master visualization

[PaoloVallesi]

How to reproduce:

1. Add the object created with this extensions as master visualization
2. Open dev-hub in Single configurator, and select the master visualization added in step 1

The extension will load with labels and stuff but bars do not appear.

The same behavior occur if that object is added to a mashup

I am having a similar issue when adding it as a master visualisation and trying to use it with Qlik dashboard bundle Tabbed Container. It may be related, if not i will raise a separate issue.
