Possible bug with calendar widget - range selection?

[Vedad]

Hi,

I am not sure if is a bug or something configuration specific, but I have the following behavior in the calendar app:
I am using base range selection configuration for my kendo ui angular calendar. 
After I select first date, say 15.12.2025. and i want to scroll to say june 2026, to select second date, I scroll with mouse (mac os, Sequioa 15.7.2) or touchpad, around March, calendar jumps back to December. 

If I scroll on the side wheel with months to June, moment I go to the calendar to select dates, it jumps, but if I click on the June, then it doesn't jump back.

The same behavior is visible at Kendo UI demo page

App is built in angular 20 and it is a standalone component.
Is this a bug or expected behavior? 

Thank you.
Vedad
