Change Details

User-specific html must not be added to the `ParserOutput` (cache). The "old" `PlaceholderEmittingEntityTermsView` Termbox prevents that by rendering placeholders in place of the user-specific markup. The new Termbox has to implement some way to ensure that no user-specific markup (e.g. toggle state, language preferences) is added, possibly by rendering the Termbox for logged-in users at a later point in the request life cycle, e.g. on `OutputPageBeforeHTMLHookHandler::doOutputPageBeforeHTML`. This has to be solved before deployment.

**AC** Implement the proposal defined in the [Termbox and ParserCache Integration ADR](https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Wikibase/+/487038). **Background** User-specific html must not be added to the `ParserOutput` (cache).
