If the delete rows button is used on a table that is followed by another table, and all the rows from the first one are deleted, the next table receives focus. Upon clicking the delete row button again, an error is being thrown "Cannot read property 'rows' of undefined".

• create a table
• create a table immediately following the first
• focus the last row of the first table and click the 'Delete row' button until all rows are deleted.
• Click the 'Delete row' button again.

Horizontal and vertical lines appear in the merged Spreadsheet cells when they are disabled.

** Possible workaround could be to apply the following CSS:

      #spreadsheet > div.k-spreadsheet-view > div.k-spreadsheet-fixed-container > div.k-spreadsheet-pane > div.k-spreadsheet-data > div.k-state-disabled {
        opacity: 1;

      }

Reproduction of the problem

1. Open this Dojo and run it
2. There are is a horizontal line above the cell with text "Merged DISABLED cell and there is a horizontal line above". There is a vertical line inside the cell with text "Two cells are merged horizontally and the result cell is disabled. There is a vertical line that should not appear"

Current behavior

When Spreadsheet cells are merged and the result cell is disabled, there are horizontal or vertical lines that appear inside the merged cell.

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
* **Browser:** [all] 

Feature request

The Kendo UI ToolTip exposes the AutoHide functionality. However, this option could not be configured for the labels' tooltip of the Kendo UI Chart

Expected/desired behavior

Be able to configure the AutoHide of the chart's tooltips. When the user hovers out, the tooltip should be persisted until a mouse click is present.

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all] 

The most important part of using Vue especially in Mobile, is it's small size and performance. Unfortunately, Kendo UI's Vue components are wrappers around jQuery which is something we are trying to avoid in our  ongoing developments.
I'd like to suggest building NEW Vue components in full native format with no despondency on other none related frameworks.

Thanks!

Currently, after export to excel and opening the exported file again in Spreadsheet, the row heights for rows with predefined height change. The above could be easily observed on the Index demo:

* initially, the height of the top row is set to 70px;

* export the Spreadsheet to Excel;

* after re-importing the above file, the height of the first row "Invoice #52" becomes 81px without any apparent reason.
