Noticing a scroll delay with visibleStartTime

[chuckn0rris]

Calendar should open on visibleStartTime position initially

Forum post

Hello,

I'm running into a bit of an issue with the visibleStartTime setting, which seems to take a moment to apply when set to an hour later in the day. This is reproducible on the demo calendar https://www.bryntum.com/products/calendar/examples/basic/ but it's significantly more noticeable when Bryntum Calendar is in an LWC.
If you add

modes: {week: {hourHeight:70, visibleStartTime: 18, }}

to the demo calendar on browser, when the calendar loads, the top most hour mark shown is 12:00AM, and it takes a moment for the calendar to then scroll to 6:00PM. On the LWC demo calendar there is a much longer delay until the calendar scrolls to the specified visibleStartTime.

For the browser demo calendar, there is no delay if visibleStartTime < 10, but there is a delay if visibleStartTime >= 10.
For the LWC demo calendar, there is no delay if visibleStartTime <= 10, and there is a delay if visibleStartTime > 10.
This issue is still reproducible on Bryntum Calendar version 5.6.0
I attached screen recordings of the problem for the LWC demo calendar and for the browser demo calendar where I set visibleStartTime to 18.

Our goal is that we'd be able to open the calendar so that a particular event is in view and immediately interact with that event, but we're finding that when the visibleStartTime is greater than 10 there is a delay until the calendar actually scrolls to that time.

Please let me know if there is a way around this behavior or if we can try a different approach. Thank you
