Steps to reproduce

Click the Toggle button twice, the <Home> component missing.

What is expected?

<Home> and <About> components can be switched back and forth.

What is actually happening?

When switch to <About> component with root comment, <Transition> breaking.

Console does not have any warning.

System Info

No response

Any additional comments?

I think it should log a warning to admonish this usage, if this is a limitation.

This look like 'Transition Modes' problem.

I have the same problem.
