Add defensive checks for the trap focus implementation
If the last element in the window has tabindex="-1" or the last element is hidden using "display: none", the focus is no longer trapped inside the window and can go to elements outside of it.

Just for reference:

Here is a simple REPL demonstrating the problem with "display: none" by combining two standard Telerik components, "TelerikWindow" and "TelerikTabStrip": https://blazorrepl.telerik.com/cIENwylx16bIoHrU57

Here is a simple REPL demonstrating the problem with "tabindex: -1" by combining two standard Telerik components, "TelerikWindow" and "TelerikGrid": https://blazorrepl.telerik.com/GSaXQelH31FUphsD07

 

I am not sure combining two standard Telerik components can be considered a "scenario [that] is uncommon" ...

Hi Stefan,

Thank you for sharing your thoughts on the item.

I can confirm that the Window component adheres to the official accessibility standards, following WAI-ARIA best practices for keyboard navigation based on its role. It's also tested with popular screen readers to ensure compliance.

In this particular case, the behavior is not classified as a bug because the keyboard navigation design did not intend to include elements with "display: none" or "tabindex -1" as navigable items. This scenario is uncommon. If the focus did not work correctly on actual focusable elements, we would have considered it a bug rather than an enhancement.

Regards,

Important: This is not a feature but a bug. It means that the software does not meet our customers' requirements when checking accessibility. Please change the type. Thanks.
