Version 12.0.0 removed the .k-item class from rendering on a tab strip's tab but that now means that the active tab looks identical to all other tabs. Is there a workaround or some way to get that back without manually recreating the CSS myself? 

 

The screenshot is from the docs to show it's not just my project or any custom config on my end:

Hello Alex,

Indeed, the app that hosts the auto-running examples in the documentation is currently using an outdated theme. We are aware of the problem and will fix it. Sorry about the confusion.

You can see the true TabStrip appearance on the official demo site.

I am also having this issue in my app after updating to 12.

we are loading this theme  <link href="_content/Telerik.UI.for.Blazor/css/kendo-theme-default/all.css" rel="stylesheet" />

@Andrew - can you please rule out a potential browser cache problem? Or is it possible that the app loads two Telerik themes with the second one being older?

If the above assumptions do not prove to be true, please send a live URL or a small runnable test app for inspection.

Not working for us either. Tried a clean solution and on different App service + machine. The result is the same

@dimo
Seems that I have forgotten to update our npm version. After that active worked again.
