Discoverability follow-up to #3588057 (closed as won't fix in favour of #3588108 in domain_extras).
Problem
Per-domain configuration can affect rendering that depends on language-keyed plugin definitions cached by Drupal core (LocalTaskManager, LocalActionManager, ContextualLinkManager). Without a cache key that also varies by domain, the first domain to warm the cache wins and subsequent domains render stale tabs and actions.
The fix lives in the new domain_menu_extras submodule of the domain_extras companion project, but a reader of domain_config_ui's docs has no signpost pointing at it.
Proposed change
Add a short Related submodules section at the end of docs/domain_config_ui/index.md (and the FR/ES siblings) describing the symptom and pointing at domain_menu_extras. One paragraph per language. Technical terms (local tasks, local actions, contextual links, cache key, plugin managers, domain-aware) stay in English in the FR/ES versions, with the prose reformulated rather than translated word-for-word.
MR to follow.
