The demo doesn't work fully in any of the latest browser version other than MS Edge

[brahma-dev]

Chrome - Shows correct tab count, 1 master, but clicks on buttons don't work

Firefox - Tab count = 1, all tabs are master, clicks on button don't work

Opera - Tab Count = 0, doesn't event detect master, clicks on button don't work

But surprisingly it works in Microsoft Edge.

@brahma-dev Did you found a solution?
Maybe another library, which implements primary/secondary tabs mechanism?
