Vue3 "Cannot read property 'isCE' of null" issue reproduction project.

How to run?

$ yarn && lerna bootstrap && yarn start

Navigate to http://localhost:3000.

Expected result.

You should see two lines of text

1. Host content
2. test remote component

Actual result.

Server crashes on renderSlot function with Cannot read property 'isCE' of null error.

P.S.

Removing <slot /> from remote component fixes the issue, but of course we need slots in our code :)
