Bug report

According to the accessibility spec, when the ColorPicker's popup is open, and the focus is on the last focusable element, pressing tab should focus the first focusable element in the popup. Instead, the focus moves out of the popup, to the next focusable element on the page.

Reproduction of the problem

1. Open the Keyboard Navigation demo - https://demos.telerik.com/kendo-ui/colorpicker/keyboard-navigation
2. Open either of the ColorPickers
3. Press tab until you focus the last focusable item in the popup

Current behavior

Pressing tab again moves the focus out of the popup

Expected/desired behavior

Pressing tab should preserve the focus within the ColorPicker, to the first focusable item
