Hi,
please help
If html content with contenteditable, then not work paste images from clipboard.
Maybe a paste process needs to be process handled somehow?

Converting to discussion as bug report was not completed.

You'll need to test with the CEF Sample application (cefclient) to confirm the behaviour you are after is supported.
