### Electron Version

### What operating system are you using?

Windows

### Operating System Version

Windows 10

### What arch are you using?

x64

### Last Known Working Electron version

_No response_

### Expected Behavior

If a BrowserView that contains a draggable region (-webkit-app-region: drag) is moved (has its bounds changed) within a BrowserWindow, the draggable region should effectively move with the BrowserView.

### Actual Behavior

The draggable region does not move when the BrowserView does. The previous absolute BrowserWindow region remains draggable, and the new region the BrowserView occupies is not draggable.

### Testcase Gist URL

https://gist.github.com/bff9757ccf3613446232a03f08bd8075

### Additional Information

Gist is fairly straightforward, as you move the view down, the original location of the draggable bar is the only draggable region.
