minDate and maxDate ignored with custom days

[yemartin]

Bug description

When using minDate or maxDate with custom days HTML, these limits are ignored when the day number is wrapped: a day rendered simply with

{{day.number}}

will be properly non-clickable when outside the minDate..maxDate range. But a day rendered with

<span>{{day.number}}</span>

will be selectable.

How to reproduce

{{#power-calendar
  selected=selected
  onSelect=(action (mut selected) value="date")
  as |calendar|}}
  {{calendar.nav}}
  {{#calendar.days minDate="2100-01-01" as |day|}}
    {{#with (format-date day.date 'd') as |weekday|}}
      {{#if (or (eq weekday "6") (eq weekday "0"))}}
        <span style="color: red;">{{day.number}}</span>
      {{else}}
        {{day.number}}
      {{/if}}
    {{/with}}
  {{/calendar.days}}
{{/power-calendar}}

Expected behavior

No days are selectable

Current behavior

Saturdays and Sundays are selectable.
