• I have searched both open/closed issues, no issue already exists.

CefSharp Version

130.1.90

Operating System

Reproduction Steps

Create simple index HTML file with only

<script>
    document.addEventListener('paste', (event) => {
        console.log('Paste event detected!');

    });
</script>

to log the copy paste event on to the console

Expected behavior

when pressing crtl+c - crtl+v the event should just occure once
