Inconsistent row reordering behavior

[zstoyanova9]

Description

When the built-in row reordering functionality is configured for the Grid, there seems to be inconsistency in the reordering behavior - some rows are prohibited from dropping at all, although there is no noticeable reason for it.
The inconsistent behavior is also reproducible in the row reordering demos on the site - https://www.telerik.com/kendo-angular-ui-develop/components/grid/rows/reordering

Steps To Reproduce

1. Open the following demo - https://www.telerik.com/kendo-angular-ui-develop/components/grid/rows/reordering#row-reordering
2. Start to reorder the rows without any particular course of action.

The row reordering behavior of the Grid should be consistent for all rows.

This can be reproduced when we quickly catch and reorder rows. I think it happens with every even row we catch.
