Expected Behavior

Calling BrowserWindow.fromWebContents(web) where web is the WebContents of a BrowserView that belongs to a BrowserWindow currently returns the associated BrowserWindow.

As such, I would expect calling BrowserWindow.fromWebContents(web) where web is the WebContents of a WebContentsView that belongs to a BrowserWindow to return the associated BrowserWindow.

Actual Behavior

Calling BrowserWindow.fromWebContents(web) where web is the WebContents of a WebContentsView that belongs to a BrowserWindow does not return the associated BrowserWindow.

Hey @neobyteUK, I actually think this is expected behavior - we can consider changing this as a feature in the future, but as of right now, I don't think we expect that the BrowserWindow value is returned here

Closing in agreement with above - when a WebContents belongs to a WebContentsView, it may or may not be attached to a BrowserWindow. Event when the WebContentsView is attached, its webContents are not strictly owned by the BrowserWindow.
