Hi,

You prob. already know this, but in Chrome attribute autocomplete should be "disabled" instead of "off" for e.g. combobox - then we don't get the auto fill.

Even thought it has no id nor name - I think it looks at the lavbel - in my case its "Name" and the combobox get a big Chrome auto fill from the address book. Setting it from "off" to "disabled" will disable both auto complete AND auto fill.

The same goes for the AJAX Combobox - will you notify that team too? Current hotfix for that is `$(".rcbInput").attr("autocomplete", "disabled");`

Thanks

/Anders

Hi Support,
I have some issues with the copySelectionToClipboard Method for the Grid widget. 

In the first one, the copy function of the table seems to have a problem with locked columns. In the dojo of the first problem the table headers are displayed shifted.

Secondly, grouped table headers are not copied. To see in the second dojo.

Lastly, it should be mentioned that the definition for the copy method is not included in the kendo-ui npm packet. 

Problem 1:
https://dojo.telerik.com/OBOQemUm

Copy result in Excel:

Problem 2:

From package "@types/kendo-ui": "2020.1.0" i found;

Hello, the Excel Export doesn't export the columns headers sums (view in image).

Is it possible export to Excel columns headers sums?

Describe the bug
In IE11 on resizing horizontally the browser window, the text of the ToolBar's tools overlaps.

To reproduce
Steps to reproduce the behavior:

1. Open: dojo example in IE11.
2. Resize the browser window making it narrower.

The tools size is not properly calculated and text overlapping can be observed (see the screenshot linked below). Overflow hidden is not set to the button tool and the k-input elements are resized on resizing the browser window.

The following CSS rule can be used as a workaround:

.k-toolbar .k-button,
.k-toolbar .k-input {
  overflow: hidden;
  flex: 0 0 auto;
}

Expected behavior
The ToolBar tools should properly resize on browser window resize. No text overlapping should occur.
