Follows-upc578db02andea671b1f, which I thought removed all code relating to the old async EventLogging method. I didn't notice this UI code at the time, because I only took a single pass over the code to find dead code. Now that that code is gone, it is clear that the UI code is also redundant. The mw.track() and logEvent() methods don't track the Beacon API's async fetches, which also isn't needed, since the loss of browser context upon navigation doesn't abort background beacons. The loading of the EL library itself is already ensured via a dependency so we already know there won't be an async fetch for that. What that leaves is some portion of older browsers in which a EventLogging falls back to 'new Image'. This is basically just IE 11 per <https://caniuse.com/beacon>, and for those some portion of events will have been lost since EventLogging removed support two+ years ago for tracking those fallback fetches via a Promise (because of the perf issues caused by what the removed code here was able to do).

== Universal Language Selector == The Universal Language Selector extension (ULS) provides a flexible way to configure and deliver language settings like interface language, fonts, and input methods (keyboard mappings). This will allow users to type text in different languages not directly supported by their keyboard, read content in a script for which fonts are not available locally, or customise the language in which menus are displayed.

See GPL-LICENSE and MIT-LICENSE for details. == Installation == For a very, very quick start add the following lines to LocalSettings.php of your MediaWiki setup: wfLoadExtension( 'UniversalLanguageSelector' ); By default, ULS will appear at personal toolbar position. If you want ULS at interlanguage position, add the following line: $wgULSPosition = 'interlanguage'; == Developers == The MediaWiki Universal Language Selector project uses jquery.uls: https://github.com/wikimedia/jquery.uls Its development is at Wikimedia Github account. Any fixes to lib/ should happen at Github. Follow the build instructions of jquery.uls to create jquery.uls.js. Bugs for the extension are handled in Phabricator: https://phabricator.wikimedia.org/tag/mediawiki-extensions-universallanguageselector/
