### Electron Version

15.2.0

### What operating system are you using?

Windows

### Operating System Version

Windows 10 version 20H2

### What arch are you using?

x64

### Last Known Working Electron version

15.1.2

### Expected Behavior

Apply `setContentProtection` function without any effects on the application window behavior on `browser-window-created` event.

### Actual Behavior

When `setContentProtection` function is called on `browser-window-created` event, the application window form will changed when the focus is backed.  The value of the argument of `setContentProtection` has no effect on the result.

### Additional Information

When I call `setContentProtection` just after creating `BrowserWindow`, this issue does not happen. But I want to set contents protection on each windows which are created by `new-window` event. Therefor, I have called `setContentProtection` function on `browser-window-created` event.
