When using
navigateTo, there are certain conditions which can force therender()function of thenavEntryInstanceto be called multiple times. The problem is that a key is generated during the render function, and the key generation function has a global incrementing counter. When this occurs, a new navEntryItem is created, which the frame seems to dump promptly, or Vue ignores.To be honest I haven't delved deeply into the inner working of the frame, or really understood how the render function gets called multiple times. Regardless, it does and ensuring that a unique key is only generated once will keep Vue happy.
