See this profile https://perfht.ml/2BplrGf from bug 1425398. The code is: https://searchfox.org/mozilla-central/rev/ff462a7f6b4dd3c3fdc53c9bc0b328f42a5b3d2b/browser/components/preferences/in-content/main.js#1030 This seems to be a hack to force a synchronous attachment of a XBL binding, but I would be surprised if this was still needed after the preference reorganization.
