Bug report

Reproduction of the problem

Dojo example.

1. Type in "f" in the MultiSelect's input area. It is filtered and shows 2 items in the list.
2. Press "Ctrl + A" keys. The two items are selected.
3. Clear the text in the input. The list is populated with all items in the dataSource.
4. Press "Ctrl + A" keys again

Current behavior

All items are selected, but the first two ("Chai and Chang") are not highlighted as selected.

Expected/desired behavior

All items should be selected and highlighted as selected.

Environment

• **Kendo UI version: 2020.3.1118
• jQuery version: x.y
• Browser: [all]

Hi.

In Kendo UI for ASP.NET MVC, I'm able to import the following file types into the Editor:

Docx

Rtf

Html

Plain Text

I'm also able to export to the following file types:

Docx

Rtf

Pdf

Html

Plain Text

I expected this functionality to also exist in the Editor control in Kendo UI for ASP.NET Core.

This functionality seems to be missing from Kendo UI for ASP.NET Core.
