Environment Details:

Repro Steps:

1. Launch #URL: https://fluentui-blazor.net/DateTime#defaulttimepicker
2. Tab to "Days view" Date form field.
3. Observe that the calendar control associated with the form field is not accessible through Keyboard.

Actual Result:

The calendar control in the “days view” doesn’t work with keyboard keys like Enter or Spacebar. It only opens when you click it with a mouse.

Expected Results:

The Calendar control associated with the Date form field must be accessible through Keyboard keys.

User Impact:

Keyboard users are impacted due to the inability to activate the calendar control via keyboard keys.

Indeed, this component is not compatible with accessibility features, as explained in the documentation.

We will work on it.

I pushed this PR #2688.

The user can navigate, using keyboard (Tab and Enter), into the Calendar or DatePicker components.
But not yet using the arrows to navigate from day to day (or month to month).

@ManishaC1 Can you confirm that this is an acceptable first solution? We'll create another update later to add navigation arrows.
