If date is disabled & selected, it should still have class selected

[swrobel]

When using "multiple" mode and disabling a selected date, it only receives the class flatpickr-disabled and not selected. This choice seems to be intentional, but I think it should have both classes. Use case: I want to show users dates they've selected in a previous session, but not allow them to remove those dates, only add new dates.

Current:

<span class="flatpickr-day flatpickr-disabled" aria-label="August 30, 2019">30</span>

Should be:

<span class="flatpickr-day selected flatpickr-disabled" aria-label="August 30, 2019">30</span>

Similar to: If "today" is disabled it should still have the class "today"
