Grid with loaderType "skeleton" does not display data in endless scrolling scenarios

[IvanDanchev]

Bug report

Reproduction of the problem

Dojo example: https://dojo.telerik.com/@sspasova/OdOwagUY

1. Scroll the Grid

Current behavior

The data is requested, but it is not displayed in the Grid.

Expected/desired behavior

The data is displayed, regardless of the type of loader used.

Environment

• Kendo UI version: 2024.1.130
• jQuery version: 3.4.1
• Browser: [all ]

[K-Diderot]

Additionally [or more recently], loaderType:'skeleton' clears the already populated grid data entirely upon clicking Save Changes. Clicking Save Changes a second time, oddly enough, repopulates the grid.

Filtering has some additional, very unexpected, effects but as this has been around for a while I'm not sure a deep dive would be worth the time. Simply put, filtering on a column and editing said column prevents the grid being cleared on Save Changes and it operates as expected [only if that filtered column is edited though]

I've added a stripped down example on the Kendo UI Dojo: https://dojo.telerik.com/EmaherIF/3

• this issue was introduced sometime after Kendo UI v2023.3.1010 [jQuery] and includes Kendo UI v2024.1.319.
