Don't leave focus mode if focused on a grid cell and user presses escape (#12652) One of the common keyboard convention is to use the escape key to restore grid navigation while the focus in on a widget inside one of the cells. However, when user press escape in such situation, NVDA instead switches to browse mode. This causes confusion, especially since there are also no messages announced to the user about this switch or any instructions on how to switch back. Description of how this pull request fixes the issue: By adding the grid cell to the existing set of controls that don't process escape outside browse mode. Testing strategy: See https://www.w3.org/TR/wai-aria-practices-1.1/examples/grid/dataGrids.html Enter the grid, arrow around, hit escape, ensure that NVDA doesn't switch back to browse mode.
