/**
 * Rather than use an existing element, we have a specific element for designating
 * the separation of certain elements by a semicolon.
 * This is a variant of the rule mw-changeslist-separator rule above but uses a semicolon
 * rather than a the two dots. It's not clear why we use different things for separation, and
 * when adding this I was unable to see any information that led to its change. A designer in the
 * future of a developer who has the energy to invest may explore this more and see if these two
 * classes can be combined.
 *
 * There is lots of context on this rule in https://phabricator.wikimedia.org/T233649
 *
 * # History page
 *
 * The history page should never have a semicolon as there is never a mw-title element.
 * Previous attempts to add the semicolon used the timestamp and a before pseudo element
 * but this led to problems as the history page also uses this element and there is no
 * easy way to distinguish it from other elements and never any need to have a semicolon
 * on the history page.
 *
 * # Special:RecentChanges
 *
 * has always had a semicolon and motivation for moving this change here.
 *
 * # Special:Watchlist
 *
 * Note that before this change was introduced, the Special:Watchlist page
 * didn't have a semicolon after the title. This caused some confusion to
 * editors (https://phabricator.wikimedia.org/T237685) but this rule makes it
 * consistent with Special:RecentChanges. To disable the semicolon on the watchlist
 * would be additional CSS to reset the content of this pseudo element for that specific
 * page, but we should not accrue that technical debt without some strong arguments for
 * doing so - and they should be documented!
 * # Special:Contributions
 * Never use semicolon on this page. Always use “. .” as separators.
