Tabstrip focus not changing from default tab

[Biswajit]

I am working on tabstrip and have created 3 of them.

One tabstrip has a .Selected(True) to be open when page is loaded initially.

But, the issue is, when I click on other tabs it does not respond in the 1st attempt (content is displayed below the content of 1st tab).

But, on 2nd attempt the tabs are working, although the focus is still consistent on the 1st tab, and it's not changing as we navigate to other tabs.

What might be happening here?

As you can see here, focus is on both Paris and Moscow, but actually it should only be on Moscow.

Hello Biswajit,

I tried to reproduce the problem, but on my side, everything seems to be as expected. In the following demo, everything seems to be working correctly too:

What I can recommend you is to check for any custom scripts or styles that may affect the behavior and the appearance of the TabStrip. Also, check for any JS exceptions in the dev tools console of the browser that might be the reason for such a broken behavior.
