When the same browserView is added to a browserWindow multiple times, the visibility of the pages in the browserView does not change.

Additional Information

After the BrowserView module was refactored in Electron 30, the behavior of the addBrowserView API changed. When the same browserView is added multiple times to a browserWindow, the browserView will first be removed and then re-added.
Specifically, this causes a jump in the page's visibility inside the browserView, and the visibilitychange event is triggered unexpectedly.

The impl of 'addBrowserView' in different versions:
electron 29: https://github.com/electron/electron/blob/v29.4.6/shell/browser/api/electron_api_base_window.cc#L762
electron 30: https://github.com/electron/electron/blob/v30.0.0/lib/browser/api/browser-window.ts#L178
