Some extensions, like Blackout, intentionally interfere with standard operation of MediaWiki and cause browser tests to fail. Extensions should have some way to signal to quibble that browser tests should be skipped for that repository.
Note: all those extensions have been migrated to a Quibble job that passes --skip selenium.
