Hi 

Noticed an issue with Tree list pagination, after applying filter.Please find attached screen recorder for the same.

Same issue i had in my application, which was able to reproduce using the  Telerik Demo's from https://demos.telerik.com/kendo-ui/treelist/index

--When it first load and minimize/collapse the parent it correctly shows page 1 as available pages.

-->Then Apply filter as shown in recorder, which then shows pages up to 5 where there were no records to display from page 2 to 5. Which is quite misleading.
 
Please find attached recorder.
