- Restoring a backup left the calendar manager standing over the import
screen, so the target picker sat hidden behind it.
- The past-events preview consumed drags as well as taps, which stopped the
picker scrolling when the gesture started on the preview.
- The recurrence preview dropped DTSTART when the rule's weekday picks missed
the start's own weekday; RFC 5545 keeps it in the set.
- "This month" showed the month name in the range picker, reading as the whole
month next to options that name a concrete span.
The four files also carry their share of the comment trim from the previous
commit.
