Multi-day event is partially visible when hidden by dayMaxEvents with eventOrderStrict

Reduced Test Case

Bug Description

eventOrder is default order.
eventOrderStrict set to true.
dayMaxEvents set to 2 on DayGrid, while dayMaxEvents set false on TimeGrid.
The PB event is a multi-day allDay event, range from 19th October to 21st October.

Outcome:

• TimeGrid shows the PB event under MA event, this is correct, as the start is after MA event.
• DayGrid shows the PB event differently, on 19th it is hided in more link because the dayMaxEvent set to 2
• While on 20th it shows half of the event.

Expected result:

• PB event is a multi-day event should either show all or hide all, but not show in half.
• PB event should hide in more link if part of it is unable to display.
• My expected result is attached as the 3rd screenshots.

@kaiwenlau , thanks for this thorough bug report. I can see there's a bug.

I am currently using version 6.1.8 and still experiencing this issue. When can we expect a fix for this problem?

Updated repro with v6.1.11 (still not fixed):

The bug is less severe than I originally thought. The calendar is trying its best to display 2 events max per day while maintaining strict order. I supposed we could tweak the behavior to prevent events whose start-dates are not displayed from showing. Though I bet some people might actually want this behavior in some cases. We could potentially introduce a flag to to prevent against this behavior.

We are having the exact some problem (parts of a multi-day event are disappearing) even without strict ordering. At first we thought this happens on particularly full days, but it is happening even on moderately full days, e.g. 1 or 2 other events. Since this affects the reliability of the calendar, we are eagerly looking for a fix or workaround. 🥺
