Actual Results

When the user presses the Esc key to close the "Country Code" dropdown within the "Subscribe to updates" or "Subscribe to Incident" non-modal dialog, the entire dialog closes instead of just the dropdown.

This results in a poor experience for both screen reader and keyboard-only users.

Expected Results

Ensure that pressing the Esc key closes only the currently open dropdown. It should not dismiss the parent dialog or interface. After the dropdown is closed, keyboard focus should return to the dropdown trigger element.

In this case, update the script to ensure the Esc key closes only the active dropdown, not the entire dialog.

Workaround

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