Steps to reproduce

1. use a teleport, and set it's disabled prop is true;
2. put some components inside;
3. make the teleport unmount (e.g. v-if, switch route, or other...);
4. these child components will not be unmount.

What is expected?

These child components will be unmount.

What is actually happening?

These child components will not be unmount.

I would like to point out that I encountered the exact same problem. In context I used Teleports to simulate the z-index property in a SVG tree, the feature being especially convenient for this. However this issue forced me to change the structure of the app, to avoid using Teleports. So merging the pull request would be very nice :)

I have same error，is there any progress?

in my case，i use the following methods to solve

render () {
   return disabled ? children : <Teleport>{children}</<Teleport> 
}

Same issue here
