How can I move the window without titleBar and fully filled with webView?
<p>I'm working on something similar to the native picture in picture.</p>

<p><a href="https://i.stack.imgur.com/rQ0CO.png" rel="noreferrer"><img src="https://i.stack.imgur.com/rQ0COm.png" alt="My window" title="my window that I can&#39;t move"></a></p>

<p>I want to move this window, but can't because there is no titlebar (it's hidden and <code>window.stylemask</code> is <code>fullSizeContentView</code>) in it and it's fully filled with the webView. </p>

<p>So, I can't just click on titlebar and drag to move this window.</p>

<p>P.S.
Sorry for my english. I hope the goal is clear</p>
