Reproduction:

1. Run sample at https://dojo.telerik.com/@GaloisGirl/iGArIqup/3
2. Try to heighten item A or C

Actual result: only item B can be heightened

Expected result: all items can be heightened

Reproduction:

1. run dojo at https://dojo.telerik.com/@GaloisGirl/aPUgEvUZ

Expected result

1. First header reads "Text header 1"
2. Second header reads "Template header"

Actual result

Cause

In the "_initContainers" function, when looping over containers, the variable "headerContent" still holds the content of the previous header.

Bug report

When a draggable item that is part of a tile of the Kendo UI TileLayout is dragged, JavaScript errors are thrown. This is due to the fact that the Draggable widget, internally used, calls the drag event of the widget instances inside the TileLayout.

Reproduction of the problem

1. Edit the live demo in a Dojo: https://demos.telerik.com/kendo-ui/tilelayout/index

2. Make any of the grids, resizable or groupable.

3. Resize or group a column.

4. JavaScript errors are thrown.

Environment

* **Kendo UI version:** 2020.2.617
* **jQuery version:** 1.124
