How to make changes to a document in DesignMode programmatically so that they can be undone?

[techNIKtos]

Hi,
How can I change the document loaded into WebView2 programmatically (DesignMode) so that these changes are included in the input history and then they could be undone using the 'Ctrl+Z' hotkey or context menu?

Version
SDK: 1.0.1462.37
Framework: Winforms
OS: Windows 10

My use case: I use WebView2 in DesignMode as an HTML editor. It works well. But I have an issue: when I change the content, it is not added to the input history, and undo/redo is not worked with these changes.

I used 'getSelection', 'clipboard', 'appendChild', 'insertBefore', etc. in the script. And all changes made in this way cannot be undone using 'Ctrl+Z'. I didn't find API for a built-in UndoManager and the implementation of custom UndoManager can be problematic and related to other issues, for example, how to link together built-in undo/redo feature and the custom UndoManager.

I found that if I use 'execCommand' instead, than undo/redo will work. But the execCommand is marked as deprecated. Is it safe to use the 'execCommand' in the script for WebView2 now, or is there an alternative way to achieve the desired behavior?

Thanks.
