Steps to reproduce the problem:
1. Use for example chrome-remote-interface
2. Input.dispatchMouseEvent({
            type: 'mousePressed', button: 'left', clickCount: 1, x: 50, y: 50
        });
3. Input.dispatchMouseEvent({
            type: 'mouseMoved', button: 'left', x: 600, y: 600
        });
4. Input.dispatchMouseEvent({
            type: 'mouseReleased', button: 'left', clickCount: 1, x: 600, y: 600
        });

What is the expected behavior?
Emulate a drag and drop from starting at (50,50) and ending at (600,600)

What went wrong?
Did not generate a drag and drop. 

Did this work before? N/A

Find a simple repro-case: 

const CDP = require('chrome-remote-interface');

const html = `
<div style="position:absolute;width:100px;height:100px;background:red" id="from" draggable="true">DRAG ME</div>

<script>
function dump(event) {
    const {type, clientX, clientY} = event;
    if (type === 'dragover') {
       event.preventDefault();
    }
    console.log(\`\${type} \${clientX} \${clientY}\`);
}

from.addEventListener('dragstart', dump);
document.body.addEventListener('dragover', dump);
document.body.addEventListener('drop', dump);
</script>
`;

async function test() {
    try {
        const client = await CDP();
        const {Page, Input, Runtime} = client;

        await Page.navigate({url: `data:text/html,${html}`});

        Runtime.enable();
        Runtime.consoleAPICalled(({args}) => {
            console.log(args);
        });

        await Input.dispatchMouseEvent({
            type: 'mousePressed', button: 'left', clickCount: 1, x: 50, y: 50
        });

        await Input.dispatchMouseEvent({
            type: 'mouseMoved', button: 'left', x: 600, y: 600
        });

        await Input.dispatchMouseEvent({
            type: 'mouseReleased', button: 'left', clickCount: 1, x: 600, y: 600
        });
    } catch (err) {
        console.error(err);
    }
}

test();
