"Manage Calendars" dialog's lack of minimum height causes AdwDialog to shrink to unhelpful size by default when the user has few calendars
Version 46's use of AdwDialog for the "Manage Calendars" dialog causes the dialog to be sized to be unhelpful by default, as GNOME Calendar starts with EDS' two default local calendars:
GNOME_Calendar_46_Manage_Calendars_AdwDialog_need_minimum_height
Hopefully we can still use a minimum height property with AdwDialog?
