How can we make first tab as default when dashboard is opened

[shugup2923]

Hi All,

We have a dashboard which uses three layers of tabs- (please refer attached screenshot)

Issue- when we load the dashboard, by default it opens first tab of third layer, Ideally it should be first tab of first layer. 

Splunk Version - 7.3.3
Note- we are using latest tabs.js and tabs.css file.
