WTH, why cant we use a type conditional in Glance

[Mariusthvdb (Marius)]

we can do:

type: entities
entities:
  - entity: sun.sun
  - type: conditional
    conditions:
      - entity: input_boolean.test
        state: 'on'
    row:
      entity: sun.sun

but not then identical config in a Glance

type: glance
entities:
  - entity: sun.sun
  - type: conditional
    conditions:
      - entity: input_boolean.test
        state: 'on'
    row:
      entity: sun.sun
