[TreeList] Drag selection breaks row selection

[georgi-sla]

Description

Currently, when the user selects multiple rows inside the TreeList using the drag selection mode and then tries to select/deselect one of the already selected rows by clicking either on the checkbox or on the row itself, the selection remains the same and nothing changes.

Steps To Reproduce

1. Create a Grid component.
2. Enable the selection feature.
3. Select multiple rows using drag selection.
4. Click on an already selected row or its checkbox.

Please, refer to the demo in the following article: https://www.telerik.com/kendo-angular-ui/components/treelist/selection/row-selection.

Actual Behavior

Currently, the first click on a row(or its checkbox) that has already been selected with drag selection does not perform any operation. Instead, the user should click a second time in order to get the expected behavior.

Expected Behavior

Clicking on a row that has already been selected with the use of drag selection should deselect all selected rows and should only leave as selected the row the user has just clicked on. Clicking on the checkbox of a row that has already been selected with drag selection should deselect this row.
