We are upgrading kibana from 7.0.1 to 7.8.0
We had created Control Visualization in Kibana with 3 level parental control and using this in Dashboard. This was working as expected in 7.0.1
Issue: When we upgraded to 7.8.0, we have issues in Control Visualization with multi(3) levels. When 3rd level object is selected, all the previous 2 level selections are removed automatically(Complete visualisation selection are cleared as if it is a "CLEAR FORM" button is clicked.).
Screenshot after two level selection.
The moment we will select third field entire forms cleared.
Observation: In 7.0.1, there was only one API call(observed through inspect option of browser) made when 2nd level object is selected and no API calls made for 3rd level object selection. While in 7.8.0, we see there are 2 API calls made for every 2nd level object selection and also there are 2 calls made for 3rd level object selection and then all selections are removed automatically.
