Only the selected tab has an aria-selected attribute. According to the documentation I can find, all tabs should have aria-selected, and be set to true or  false as appropriate.
https://www.w3.org/TR/wai-aria-1.1/#aria-selected

aria-selected (state)§

Indicates the current "selected" state of various widgets. See related aria-checked and aria-pressed.

This attribute is used with single-selection and multiple-selection widgets:

  1. Single-selection containers where the currently focused item is not selected. The selection normally follows the focus, and is managed by the user agent.
  2. Multiple-selection containers. Authors SHOULD ensure that any selectable descendant of a container in which the aria-multiselectable attribute is true specifies a value of either true or false for the aria-selected attribute.

Any explicit assignment of aria-selected takes precedence over the implicit selection based on focus. If no DOM element in the widget is explicitly marked as selected, assistive technologies MAY convey implicit selection which follows the keyboard focus of the managed focus widget. If any DOM element in the widget is explicitly marked as selected, the user agent MUST NOT convey implicit selection for the widget.

We are using the Telerik tabStrip ASP.NET AJAX control.

We have set PerTabScrolling="true" on the tabStrip.

Then we have hidden a tab on the client side that is apart of the tabstrip.

Now when we scroll to the end of the list we receive a JavaScript error: Sys.InvalidOperationException: Cannot serialize non finite numbers.

This only happens when we hide a tab.

The disabled tabs don't look like disabled in Classic render mode. 

This issue is not observable with the 2016 release as shown in the attached screenshot.

Workarounds:
1) You can change the color of the disabled items by applying the following class to the page:

        .rtsLink.rtsDisabled {
            color: #a5a5a5 !important;
        }

2) Another option is to switch the rendering to Lightweight -> RenderMode="Lightweight".
