When an embedder's render view is deleted, the guest is destroyed,

embedder.once('render-view-deleted', closedByEmbedder)
guest.once('closed', closedByUser)

This is causing issues on Windows when WindowList::CloseAllWindows() is called since when the first window is closed, the second window will also be closed causing a crash when NativeWindow::Close() is called a second time and a crash occurs when checking the accelerated widget in IsClosable().

This pull request adds a check for IsClosed() before calling Close() to guard against this.

Not sure if this check is better to put in NativeWindowViews::Close()instead.

Closes #7074
