Currently, a modal window allows for tabbing out of the window to controls on the page below. See forum posts http://www.telerik.com/forums/tab-key-and-modal-windows http://www.telerik.com/forums/kendo-window-tab-order-and-section-508 On a web app I run into the problem where the dialog is dependent on a grid row to be present, but due to tabbing out of the not so modal window I can delete the applicable grid row removing the context on which the modal window is based. This is a bug.
Hi,
This is already available since several versions. Focus is trapped only in the modal popup: https://dojo.telerik.com/@iankodj/umeRIWAK.

This appears to have been fixed at some point.
It is a problem when you have a modal up and a user can still interact with the site behind the overlay, period.
From a UX perspective, this is a bug.
