Actual Results

No functionality is provided to close the "Blocks" non-modal dialog (available by activating the "Blocks", and "Blocks (about -1 month)" buttons). As a result, keyboard-only and screen reader users were not able to close the non-modal dialog and access the background content/page.

Expected Results

By pressing an ESC key or through a mechanism to close the dialog (e.g., close button), users should be able to close the dialog.

Provide a "Close" button in the "blocks" non-modal dialog for keyboard-only and screen reader users. Also, provide an ESC key mechanism to close the dialog.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
