This is a quick bug fix to #6561, which recently landed. I'm in the process of implementing the tests for this in Chromium.

In #6561, we forgot to clear the pointer from the node back to it's manually assigned slot when .assign() is called again on that slot. This should fix that.


💥 Error: Wattsi server error 💥

PR Preview failed to build. (Last tried on Apr 15, 2021, 1:55 PM UTC).

More

PR Preview relies on a number of web services to run. There seems to be an issue with the following one:

🚨 Wattsi Server - Wattsi Server is the web service used to build the WHATWG HTML spec.

Sigh, not known, and the health check (https://build.whatwg.org/version) seems to be working fine. Let's keep a close eye on it and if it happens again see what we can do... maybe just bump up the memory again.

The original implementation of the imperative slot distribution
API was done before the final spec PRs landed. In the process of
landing those PRs, several changes were made to the way the API
works. Primarily, there are two changes:

 1. The "auto" slotAssignment mode was renamed to "named".
 2. The "linkage" that is created by HTMLSlotElement.assign() was
    made more permanent. Previously, moving either the <slot> or
    the assigned node around in the tree (or across documents)
    would "break" the linkage. Now, the linkage is more permanent,
    and the only way to break it is through another call to .assign().
