Exceptions within periods aren't listed in exceptions template

[hughbris]

This has just come up. Reasonably obscure and there is a workaround. Business has limited operation hours for a period because of Covid-19 lockdown, and I need to include Good Friday and Easter Monday as exceptions within the period because they are non-operational days. The problem is that the exceptions display template does not recurse into the periods for exceptions.

Easily worked around by duplicating the period exceptions at the outer level, but not ideal.

Ideal:

    periods:
      - begin: "2020-03-26"
        end: "2020-04-23"
        description: Emergency operation hours
        name: "COVID-19 lockdown"
        regular:
          monday:
            - opens: "09:00"
              shuts: "16:00"

          # YADA YADA …

          friday:
            - opens: "09:00"
              shuts: "16:00"
        exceptions:
          '2020-04-10':
            hours: []
            comment: 'Good Friday'
          '2020-04-13':
            hours: []
            comment: 'Easter Monday'

Workaround:

    regular:
      # YADA YADA …
    exceptions:
      '2020-04-10': # has to be added redundantly
        hours: []
        comment: 'Good Friday'
      '2020-04-13': # has to be added redundantly
        hours: []
        comment: 'Easter Monday'
    periods:
      - begin: "2020-03-26"
        end: "2020-04-23"
        description: Emergency operation hours
        name: "COVID-19 lockdown"
        regular:
          # YADA YADA as above with duplication …
