When RadRibbonView is minimized (IsMinimized="True") and KeyTips keyboard navigation is used to select a tab via ENTER or SPACE instead of typing an access-key letter, the ribbon's minimized popup opens over the window content as expected, but afterwards neither ESC nor ALT collapses it again. The popup remains open and overlaying the window content until the user clicks elsewhere with the mouse, trapping keyboard-only users in an invalid UI state.
