This error is still happening and shows up fairly regularly near the top of logspam-watch in my experience (e.g. currently 12 occurrences in the past 60 minutes).

Seems related to T416630: TypeError: Wikimedia\Parsoid\Core\DOMCompat::getPreviousElementSibling(): Argument #1 ($node) must be of type DOMElement|DOMCharacterData|Wikimedia\Parsoid\DOM\Element|Wikimedia\Parsoid\DOM\CharacterData, null given.

Should be fixed by Parsoid: Add safeguard when checking for reflist template (1239151) · Gerrit Code Review; merging into T416630 as the root cause is the same.
