Dashboard Widget show some Appointments, other not

Steps to reproduce

1. Connect more then one Calendar
2. Assign different Colors to each of them
3. deactivate some calendars (e.g. 2 of 5)

Expected behavior

The Dashboard-Widged should just show the Calendars that are currently visible in the Calendar-view, OR (better!) there should be an selector in the Dashboard-/Widget-Card, which calendars to show!

Actual behavior

1. Appointments of all connected Calendars are shown (even if they are marked as invisible in the calendar-settings)
2. The colored circles in front of the Appointment are all BLUE, and don't have the colors of the calendar they are from
3. Other Calender-Entries are fully missing in the Widget-preview for Appointments

Here you see any (but 1) calendar activated and it's appointments.

Here is the output of the Widget:

As you see:

1. The purple marked ones are not shown at all in the Widget
2. There is an Entry Zoe which is from the Calender that is hidden (see above in the first image). Btw. even if I hide the S ...(Familie) Calendar, the output of the widget stay the same

Start by reproducing the Dashboard Widget with multiple calendars, different colors, and some calendars hidden in the Calendar view. Inspect the Dashboard Widget and calendar-visibility data flow to compare which appointments, colors, and calendar entries are displayed. Done means the widget consistently follows the intended calendar visibility behavior, preserves calendar colors, and includes the expected entries.
