Bug report

Regression introduced in R1 2021 SP1. Possibly related to #6597.

Reproduction of the problem

Reproducible in the Kendo UI for jQuery Overview demo, the MVC Overview demo, other demos, and in the attached sample project.
MVCGanttTest.zip

1. Run a demo or the project (the project requires a reference to Kendo.Mvc.dll to be added).
2. Open the dev tools Network tab.
3. Double click a child task in the Timeline view to edit it.
4. Modify the task's title, e.g., a character to the title text.
5. Save the task.

Current behavior

Multiple requests are sent to the Update action. One for the edited task and additional one(s) for the parent task(s) depending on the level of the edited task. This happens only on initial edit of that particular task. Subsequent editing results in only 1 request to the Update action.

Expected/desired behavior

Every time a task title is edited, only 1 request to the server should be sent.

Environment

• Kendo UI version: 2021.3.914
